Do You Eat Sushi?
If so, please make sure to download the 2009 Sustainable Seafood Guide for Sushi. Just click the link or the image below and print out the PDF which you can then fold into a wallet card. Did you know that our love for sushi is severely depleting many of our oceans' fishes? Bluefin tuna are in particular danger because they have been so drastically overfished. A more responsible alternative to bluefin tuna is albacore tuna (shiro maguro).

In addition to downloading your handy sustainable sushi pocket guide, also be sure to download the 2009 Seafood Watch guide for your local region, as well. We all need to take care of our oceans. Whether dining in or out, be sure to express an interest in sustainable seafood options to your grocer, chef, or restaurant. As long as they know there's consumer demand for sustainable options, they hopefully will make responsible choices about what types of seafood to supply.

And remember . . . never order the Chilean Seabass! This fish has been severly overfished to the point where there is a great deal of illegal fishing taking place. Did you know that the real name of the Chilean Seabass is the "Patagonian Toothfish"? The name was changed for marketing purposes so that it would sound more appetizing to consumers. Let's leave the toothfish alone for a while and try to let them recover. . .

Kingdom of the Blue Whale: Premieres March 9
Be sure to tune into the National Geographic Channel on March 9 for the premiere of "Kingdom of the Blue Whale." They already have some great interactive content to explore on their web site including an interactive Flash module that lets you measure the size of a blue whale as compared with school buses, Triceratops, M1A1 Abrams tanks, the Space Shuttle Orbiter, and more.

Also check out the March 2009 print issue of National Geographic Magazine for the in-depth story and some incredible photos from the field.

While whale watching in the Santa Barbara Channel in July of 2008, we came across the R/V Pacific Storm, which is a research vessel from Oregon State University and one of the home bases for their blue whale research. Here are a couple of photos I snapped of the Pacific Storm and its Zodiac boat which was out tagging blue whales. The Pacific Storm is also pictured in the March issue of National Geographic.

Whale Quest Kapalua: Maui, Hawaii
I was lucky enough to attend Whale Quest Kapalua on Maui, Hawaii from February 13-15 this year. It was an amazing event (free to the public) and I hope to be able to attend again next year. One of the things I enjoyed most about this conference was the amazing photos and videos that people brought back from the field. Jason Sturgis showed some unimaginable underwater footage of humpback whales and Adam Ravetch shared excerpts of his upcoming film, "Arctic Giants of the North." There were many informative and educational lectures, as well. To keep tabs on next year's event, visit the Whale Trust web site.

American Cetacean Society Conference: November 13-16, 2008 in Monterey, CA (registration is still open!)

The American Cetacean Society (ACS) will hold their 11th international conference in Monterey, CA on November 13-16. This is shaping up to be another remarkable conference and the conference program looks amazing.

Sessions will take place all day Saturday and Sunday and will include scientific discussions, as well as discussions about whaling, human/whale interaction, the environment and in-depth reviews related to specific whale species.

There's going to be a banquet on Saturday evening, as well as a photo contest, poster session, art show, and auction. And on Monday, there will be a free symposium on gray whales if you are lucky enough to be able to stay beyond the weekend. And if you can make it out before the weekend, don't forget to sign up for Friday's whale watch in Monterey Bay! There's bound to be some interesting marine wildlife around. Registration information can be found here. Online registration ends November 10th, but after that date, you can still register at the door.

While you're at it, consider becoming a member of ACS. I'm a proud member and have learned a lot about cetaceans by being part of the organization. In addition to educational benefits, you'll also be helping the great cause of cetacean and environmental conservation.

"Whale Wars" Television Series to Premiere on Animal Planet
This Friday, November 7, Animal Planet will debut a new 7-part weekly television series called "Whale Wars." It will follow the mission of Paul Watson's Sea Shepherd Conservation Society as they work aggressively to help stop whaling, poaching, shark-finning and habitat destruction. It's impressive that Animal Planet is devoting so much time to this important topic.
If anyone has ever been lucky enough to see a whale in the wild, it's hard to imagine that any human being would want to intentionally kill these magnificent creatures. In particular, Japan, Norway, and Iceland are still aggressively killing whales with no regard for the International Whaling Commission's guidelines.

The fact that Japan, Norway, and Iceland have such little respect for the whales and the marine ecosystem makes us seriously question whether we should be spending any money on the products or tourism of these countries. Whaling has no place in today's society--it's a brutal, unnecessary, and inhumane practice. Honestly, what is the point? Whales are in desperate need of our help. Many species are endangered as a result of whaling and their habitats are under constant threat.

Thanks to Animal Planet for taking time to educate us on this important topic.

Coastal Cleanup Day at Malibu Lagoon in Malibu, CA
This past Saturday, September 20 was International Coastal Cleanup Day, which is sponsored by the Ocean Conservancy. Here are a few photos of the cleanup efforts at the Malibu Lagoon in Malibu, CA.

On my trash scorecard, note that 53 food wrappers/containers were found. This did not even include the countless small pieces of styrofoam that were likely once a cup, food container, etc. It's awful for these things to be laying out in the open so close to bird and marine life. The animals often ingest the waste and cannot digest it and become victim to an untimely death.

With very little effort, I also found 53 cigarette butts. In addition to the fact that animals ingest cigarette butts, it's awful that so many people discard their smokes in an area that's so full of dry brush and plants. Southern California (and many other areas) are very susceptible to fire and if you recall, one of last year's fires in Malibu was thought to have been started by a cigarette that was thrown out of a car window.
Hundreds of pounds of trash was collected:

Please do your part to keep beautiful places like the Malibu Lagoon clean and free of trash. If you see trash around any coastal area, please take a moment to pick it up and help keep our environment clean.

International Coastal Cleanup Day is this Saturday, September 20, 2008
If you have a little time to volunteer this weekend, you may want to consider helping out with the Ocean Conservancy's International Coastal Cleanup Day efforts. It's a great way to help the environment and to help countless forms of wildlife that depend on coastal or wetland habitats. You don't need to live near the ocean. . . cleanup efforts will be underway in many inland areas as well. You can learn more by clicking the Coastal Cleanup Day image below and remember to help keep your environment clean all year around. If you see trash laying around outside, make an effort to pick it up, especially if it's in a coastal area.

Minke Whale Shows Partial Tail Fluke
While looking for Blue whales in the Santa Barbara Channel this past weekend, we came across what appeared to be a young Minke whale who was interacting with a California sea lion. It was interesting behavior and before one of its dives it rolled on its side and then showed us a partial tail fluke--pretty unusual behavior for a Minke whale. Here's a video clip of the action:

We also spotted at least 10 Blue whales and witnessed a team of scientists tagging the Blue whales with transmitters to monitor location. Note the small yellow/white tag on top of this Blue whale:

And here are the scientists from Oregon State University in action:

Risso's Dolphins in Santa Barbara Channel
A pod of about 50 Risso's dolphins (Grampus griseus) were active in the Santa Barbara Channel yesterday. They seemed content to casually hang around our boat for a while and there was also a small group of Pacific white-sided dolphins (Lagenorhynchus obliquidens) traveling along with them. At first glance, one of the Risso's appeared to have a dolphin slipstreaming alongside her, but as it turns out, it was a Risso's calf that was probably close to being a newborn. Here are a few photos:

Mother and calf (calf is on left, very small):

Dorsal fin of a Risso's dolphin (this scarring is the result of the teeth of other Risso's; all of the Risso's have this type of scarring):

And some other marine mammals spotted along the way--a California sea lion who was bowriding right along with a large pod of common dolphins:

Sharks Truly Need Our Help
My friend Sean hosted a screening of the documentary film "Sharkwater" last night and I highly recommend this film to everyone. Humans are decimating the shark population in pursuit of fins to make shark-fin soup. This industry is quickly destroying the entire balance of the ecosystem across our world's oceans.

Here's some data from both Sean & the movie:

- 90% of the world's shark population has been decimated over the past 50 or so years. Keep in mind that these animals have survived four major extinctions and they pre-date the dinosaurs.

- 100 million sharks are killed annually to meet the demand of the shark-finning industry.

- The majority of sharks are killed by a horrific practice called "shark finning" in which live sharks are pulled aboard a boat to have their fins cut off and then thrown back in the water to sink and die a very slow, painful death. Since there is not much room on boats, there is more space if they discard the body.

- Sharks are often caught by the "long-line" fishing practice, where fishing lines with thousands of hooks are dropped into the ocean, catching and killing countless other species such as sea turtles, sailfish, sea lions, and many other species of fish in the process. This by-catch is almost always discarded.

- Shark fins are primarily used as an ingredient in shark-fin soup, a traditional meal in Asia that was at one time available only to royalty and is often served at weddings or other special occasions. If you ever encounter shark-fin soup, please do not order it or eat it! Doing so will only further the demand for this industry. [My own recommendation is to boycott any restaurant that is serving it and to help educate the management about the troubles of this industry.]

- Sharks reproduce very slowly, some species only have two offspring every two years. Sharks cannot reproduce fast enough to keep up with the current rate of human consumption.

- 110 species of sharks are currently listed by the IUCN as a species under serious threat.

- At the rate humans are killing sharks, experts estimate that within 10 years, most species of sharks will be lost.

The "Sharkwater" documentary is available for purchase at Amazon or at www.sharkwater.com and can also be rented on Netflix. Also check out some of Sean's cool underwater pictures at flickr.

If You Encounter a Stranded Marine Mammal . . .
The following tips were provided in the 2008 Vol. 37, Number 1 issue of the Journal Of the American Cetacean Society: "Whalewatcher" (and were adapted from The Marine Mammal Center, Sausalito, CA). If you ever happen to encounter a beached or stranded animal, please observe the following precautions:

1. Don't touch, don't pick up, and don't feed the animal. Don't return the animal to the water. Seals and sea lions temporarily "haul out" on land to rest, and mothers may briefly leave their pups while at sea. A beached whale or dolphin should be reported immediately.

2. Observe the animal from a distance of at least 50 feet. Keep people and dogs away.

3. Note the animal's physical characteristics to help inform the response agency.

4. Note the animal's condition. Is it weak? Is it underweight? Are there any open wounds?

5. Note whether the animal has any identification tags or markings.

6. Determine exact location of the animal, note landmarks, and be prepared to provide accurate directions.

7. Call the appropriate response agency. To find the phone number for the authorized stranding network organization in your area, visit the NOAA Fisheries Web site.

Polar Bears Listed as Threatened Species
On May 15, 2008, the U.S. Fish & Wildlife Service organization pronounced the polar bear a "Threatened Species" under the Endangered Species Act. The loss of icy polar habitat that the polar bears face as a result of melting sea ice poses a severe problem for them. With less ice, polar bears face a much tougher time finding food and some polar bears even end up drowning because the distance between ice floes is too far for to swim. The categorization of "threatened" means that polar bears are at risk of becoming endangered in the foreseeable future. While it's very sad that things have reached the point of a "Threatened" classification, hopefully, this classification will also help focus needed resources on preserving the polar bears' pristine environment before it's truly too late for them. Here's a link to the U.S. Department of the Interior's press release on the topic and a link to polar bear information and videos from the U.S. Fish and Wildlife Service.

Ten Ways to Help Save the Ocean
Long Beach's Aquarium of the Pacific suggests following these 10 guidelines to help protect our oceans and conserve resources:
1. Eat sustainable seafood. Learn about the status of current species on NOAA's Fishwatch site.
2. Bring your own coffee mug or water bottle. Use fewer disposable items.
3. Carpool or use public transportation.
4. Bring your own bag. Carry reusable cloth bags when you go shopping. Plastic bags often end up in the ocean and post a risk to marine life.
5. Recycle as much as possible.
6. Say no to junk mail. Opt out of junk mail by visiting the Direct Marketing Association's web site.
7. Sign up to pay bills online to help eliminate paper waste and save money on stamps.
8. Protect our waterways. Watch what you wash into storm drains and do not overfertilize your lawn.
9. Choose native plants.
10. Explore the natural world! Help educate children, friends, and family members about the environment and conservation.

Marine Wildlife Viewing Guidelines
As you venture out to enjoy some time at the shoreline, please keep these viewing guidelines in mind if you encounter any wildlife. The following list is from NOAA's National Marine Sanctuaries Ocean Etiquette page (excerpts below were also taken from the print publication "National Marine Sanctuaries of the West Coast"):

1. Learn before you go. Learn more about the wildlife you may encounter before your visit.
2. Keep your distance. Getting too close to animals can be harmful both to them and to you.
3. Hands off. Not only is it often illegal touch protected species, it can also injure either you or the animal.
4. Do not feed or attract marine wildlife. Feeding or attempting to attract wildlife may harm animals by causing sickness, death and habituation to people.
5. Never chase or harass wildlife. Never surround, trap or separate animals.
6. Stay away from wildlife that appears abandoned or sick. Animals that appear sick may not be. They may just be resting or awaiting the return of a parent. If you think an animal is sick or injured, contact the local authorities.
7. Wildlife and pets don't mix. Keep pets leashed and away from marine wildlife.
8. Lend a hand with trash removal. Carry a trash bag with you and pick up litter. Garbage and fishing debris pose significant threats to marine wildlife.
9. Help others become responsible wildlife watchers and tour operators. Lead by example and support businesses that follow proper guidelines.

Japan is Still Hunting Whales
Although Japan agreed to halt their hunt of Humpback whales on December 19, 2007, they are still actively hunting both Minke and Fin whales. They intend to kill 935 Minke whales and 50 endangered Fin whales under the guise of "scientific" whaling. Although a worldwide moratorium on whale killing was enacted in 1986, Japan, Norway and Iceland have turned their backs on this international agreement and intend to kill over 3,000 whales in 2008. If you have ever been lucky enough to see whales in the wild, it's hard to fathom that they are still the targets of hunters. The methods of modern whale hunting are brutal and the whales usually die a very slow and painful death.

There are many ways you can take action to help the whales. Here are a few:

1. Contact your congressional representative to voice your opinion. The Pacific Whale Foundation has step-by-step instructions on how to contact your representative as well as text that can be copied/pasted/edited and then e-mailed. Click this link and scroll to the bottom of the page for further details. They also have a printable PDF page that you can use to collect signatures and mail to the president.

2. Donate to organizations such as the International Fund for Animal Welfare or volunteer some of your time with a local organization.

3. Consider where you spend your tourist dollars. Before planning travel to Japan, Norway, or Iceland think about whether you want to spend your hard-earned money in such countries while they are still killing whales. If you do decide to move forward with your travel, consider contacting the consulates of Japan, Norway, or Iceland to express your opinion on their whale-hunting practices.

Ongoing impact of San Francisco Bay Oil Spill Unfortunately, there is likely going to be an impact on both wildlife and the environment as a result of the Nov. 7 oil spill in the San Francisco Bay for many years to come. Over 58,000 gallons of oil spilled into the bay after a large Cosco container ship hit the Bay Bridge. Although lawsuits are in motion, the cannot do much to rescue an oiled bird or injured marine mammal. As of November 20, 2007, Audubon California had logged the following data:

Birds in care: 1,060
Birds washed: 783
Birds found dead in the field: 1,702
Birds died/euthanized: 573
Birds released: 317

This area is host to countless migratory birds and the impact could be very far-reaching due to migration patterns. The oil had also made its way to the Farallon Islands, which are home to over 200,000 Common Murres -- the largest colony south of Alaska. While most of the wildlife that was immediately impacted has likely perished by now, if by chance you do come across an oiled bird, contact the Oiled Wildlife Care Network at (415) 701-2311 or (877) 823-6926. If you live in the Bay Area and would like to help with ongoing cleanup or education efforts, contact your local branch of Audubon California. If you ever come across an injured marine mammal, do not attempt to rescue it yourself, but contact the Marine Mammal Center at: (415) 289-7325.

Third Blue Whale Found Dead
Yet another Blue whale has been found dead in the waters offshore southern California. This time, the whale was found floating belly-up in the Santa Barbara Channel and was then towed to shore to a beach at Point Mugu, where a necropsy was conducted. It was determined that the whale was killed by ship strike. The whale was male, about 60-feet long, and had multiple broken bones & ribs, as well as a smashed cranium. The Los Angeles Times reports that a great white shark attempted to attack one of the boats that towed the whale in. Other reports also say that sharks have been feeding on the whale carcass at sea.

As you can see in the photo as well as the video that accompanies this post, Blue whales often linger at the surface while they go through multiple, fairly slow breathing cycles before diving. This summer, there have been more Blue whales than usual in the Santa Barbara channel. When the whales rest in the shipping paths of large container ships, they may not be able to dive quickly enough to escape a strike.

While it's unknown whether disease or military-sonar disturbances played any additional roles, it does appear that all three deaths were the result of ship collisions. In addition to the Point Mugu whale, the Faria Beach whale (see earlier post), another Blue whale was found in the Long Beach Harbor and it likely arrived on the bow of a large container ship without the ship's knowledge. It's unfortunate that human activity has caused the loss of these whales because the Blue whale is an endangered species and each individual loss may have consequences for the future population.

In Search of . . . a Blue Whale Carcass
My curiosity got the better of me and I went searching for the Blue whale carcass that washed up on the shores of southern, CA (see earlier post). In the coming days, I will be posting many photos to the OceanSpot channel of Flickr and many videos to the OceanSpot channel of YouTube. Stay tuned for more details...

Blue Whale Carcass Near Ventura California -- Whale Death Was Caused By Ship
by Jennifer Schwartz, www.oceanspot.com

A Blue whale carcass that washed ashore Thursday evening (September 13, 2007) near Hobson County Park near Ventura, CA was towed to Faria Park in Ventura County, CA this morning.
An animal autopsy, or "necropsy," was conducted on the whale, where it was determined that the whale was female, approximately 15-20 years old (note: later reports estimated her age at 3-5 years), had been dead for about 8 days, was approximately 120,000 to 140,000 pounds, and had been struck by a ship, which caused her death. The ship strike was severe, causing a 20-foot bruise under the blubber layer of the whale, and most likely causing paralysis.
While the Blue whale is an endangered species, they have appeared in unusually high numbers in the Santa Barbara Channel this summer, most likely a result of following their main food source (krill) into the channel.

Coastal Cleanup Day at Malibu Lagoon
Today was International Coastal Cleanup day and volunteers around the world helped clean up coastal areas that are littered with far too much waste. I lent a hand at the Malibu Lagoon in Malibu, CA. The volunteer force at this site ended up collecting roughly 470 pounds of trash (or thereabouts). It was pretty amazing to see the types of junk our fellow human beings toss on the ground without a second thought. Food wrappers, plastic bags, styrofoam, cigarette butts, plastic bottles, cans, and more...the list is endless. Each small piece of trash poses a severe threat to marine and bird life. Our trash is often easily mistaken for food and if a bird or marine mammal ingests plastic, it may very well end their lives. Please don't litter! And if possible, please lend a hand to pick up trash when you see it...especially around coastal areas...you may save an animal's life.

New Whale Videos Posted
This past weekend was yet another amazing one for whale-watching in southern California. Our captain says we spotted 48 Blue Whales on our Saturday outing in the Santa Barbara Channel. Many of these whales were swimming off in the distance, but I'd say we got a close-up view of 20-25 of them. This number is hard to fathom, considering the fact that they are highly endangered animals, as mentioned in an earlier post. Despite the unbearably hot temperatures on land, it was quite chilly out on the water and the water was very rough due to high winds. As a result of the turbulent waters, many of my videos have a dizzying perspective, but there were a few good ones in the bunch and I'll be posting those to the OceanSpot Channel of YouTube. Here's a compilation of the whale videos that are currently posted on the OceanSpot Channel of YouTube. This video loop includes various of species of whales in the wild:

Seen Any Troglobites Lately?
If so, then they probably haven't seen you, considering the fact that they are eyeless. Troglobites live in caves and include various species of millipedes, spiders, worms, blind salamanders, and eyeless fish. Since they live in caves, which inherently have little, if any, sunlight, they have little need for sight and have evolved their other senses more fully.

These eyeless cave animals are known as "true troglobites," while the animals who have partial eyesight are known as "troglophiles." Troglophiles may live near the entrance of the cave, or in an area where there is partial light. The September 2007 issue of National Geographic has an interesting story about these creatures along with many interesting & mysterious photos. As with countless species of animals around the world, even these small critters face an uncertain future due to pollution, vandalism, and quarrying. (The photo in this post appeared in the National Geographic Photo Gallery about this story and was taken by David Liittschwager.)

International Coastal Cleanup Day: Saturday, September 15, 2007
If you live in a coastal region and would like to volunteer some of your time to a worthy environmental cause, consider spending part of your day helping to clean up the shoreline. Cleanups are being held in most states within the U.S. as well as in many countries abroad. Volunteers on both foot and in boats are needed. For more information, visit the International Coastal Cleanup page on the Ocean Conservancy's web site that has more information about time, location, and more details about how to help. If you can't make it out on 9/15, consider doing a little cleanup on your own time next time you see trash around a beach, a coastal region, or anywhere outside for that matter. Picking up and properly disposing of a single plastic bag can help save the live of a marine animal or bird.

Videos of Blue Whales (near Santa Barbara, CA)
This has been an amazing season for Blue-Whale watching in southern California. Whale-watching tours in the Santa Barbara area have been spotting as many as 10 or 20 Blue Whales per daily outing, which is an amazing number, especially given the fact that these are endangered animals. I've been lucky enough to get out to see them on many a weekend and have had some amazing adventures. Armed with a new video camera, I now have more footage than I know what to do with. As time allows, I'll be posting the best clips to the OceanSpot Channel of YouTube and will post some of my favorites here from time to time. Here are a couple of clips to kick things off. The first clip shows Blue Whale lingering very slowly at the surface taking a series of breaths:

The next clip shows two Blue Whales surfacing, one of which shows a bit of its rostrum (nose) as it surfaces:

The True Impact of Eating Shrimp
Are you aware of the impact our appetite for shrimp is having on the environment? According to the August 2007 issue of the Sierra Club's "Southern Sierran" newsletter, as many as 20 pounds of fish are caught, killed, and discarded as by-catch to obtain every one pound of shrimp. Shrimp trawlers rake the ocean, destroying a variety of life in their path and doing severe damage to the ocean floor. As many as 150,000 turtles are killed every year as a result of shrimp fishing. While about two-thirds of the U.S. shrimp now come from shrimp farms, the Sierra Club says that about 99% of this farmed shrimp comes from coastal areas of developing countries. Due to the billions of tons of organic waste, fertilizers, pesticides, and antibiotics that are dumped into coastal waters as a result of shrimp farming, it is believed that more than one-third of mangrove forests may have disappeared in the last 20 years. The Sierra Club recommends eating more plant-based, organic, and locally-grown food if possible. The Monterey Bay Aquarium also has a "Seafood Watch" program with handy pocket cards that offer recommendations about sustainable seafood.

The pocket cards can be printed out and carried in your wallet. They're available for the following U.S. regions: National, West Coast, Northeast, Southeast, Southwest, Central U.S., and Hawaii.
The Monterey Bay Aquarium also has more information about sustainable seafood on their web site. When it comes to your seafood meal, even small personal choices make a big difference, so keep the environment in mind before your next feast!

North Atlantic Right Whales Are Severely Endangered
If you've followed the story of the North Atlantic Right Whale, you know that the future of this marine mammal is in serious question. Right Whales are severely endangered; current estimates indicate that the population sits at around 350, a dangerously low population number for any species.

The Right Whale received its name because whalers in the previous three centuries believed they were the "right" whales to kill due to their one foot thick layer of blubber that makes them buoyant after they are killed. They could be strapped to the side of a boat and easily dragged back to shore. The whales are also very slow swimmers and mothers are extremely protective of their young, thus making them even easier targets for the whalers.

Today, the greatest threat to the Right Whale is shipping. The whales travel in the most heavily trafficked shipping lanes on the eastern coast of North America. Females migrate from the Bay of Fundy area to the southern waters off the coast of Georgia or Florida to bear their young and must again travel north (with calf in tow) to their feeding grounds. The journey is very dangerous--strikes by large ships as well as entanglements are the leading cause of death, according to the Ocean Conservancy. The death of one individual whale has severe consequences for the future of the species.

If you'd like to learn more about how you can help make the oceans a safer place for all marine life, visit the Ocean Conservancy's Ocean Action Network site. To learn more about the status of Right Whales, visit the North Atlantic Right Whale Consortium site (OceanSpot has no affiliation with these organizations, but supports their efforts to improve the conditions of our oceans around the world.

Yangtze River Dolphin Feared Extinct
It appears that the highly endangered Yangtze River dolphin, also known as the Baiji dolphin (Lipotes vexillifer), is probably extinct. According to a recent story from Time.com, this would be the first time that a species of cetacean was extinguished due to human activity...activities such as overfishing of the Baiji's target food sources, severe pollution in the river systems, a high amount of boat traffic, and lack of intervention to try to save the species. There have not been any confirmed sightings of the dolphin since 2002 and the most recent survey failed to find evidence that they still exist.

The Baiji was quite a unique creature. It foraged for food in shallow waters through the use of echolocation and was virtually blind--due to the cloudy waters in which it lived, eyesight evolved as a less-important function over time. Unfortunately, the frequent boat traffic then interfered with the dolphins' hearing, thus making echolocation, and their ability to find food, more difficult. The Baiji's demise should serve as yet another reminder that we need to be mindful of our environment and remember that we are sharing this planet with many other forms of life. The Finless Porpoise (Neophocaena phocaenoides), another resident of the Yangtze River is also at risk, but if we modify our behavior, there is still hope of saving it.

The Blues are Here!
The whale-watching in Southern California is pretty amazing at the moment. I've been out on the water looking for whales the past two weekends and am going again two out of the next three weekends. The Blue Whales are here! If you ever have the opportunity to *try* to see a Blue Whale (Balaenoptera musculus), I encourage you to do so. Granted, you may spend 8 hours looking for the whales and only about 45 minutes actually watching them, but it is definitely worth it if you have the patience and have taken your motion-sickness medication. Blue Whales are the largest creature ever to have lived on Earth and are larger than the largest dinosaurs. Their tongue weighs about the same as an African Elephant (an elephant could fit in its mouth) and their heart is about the size of a Volkswagen Beetle car. Standing beside a living creature of that size & scale is enough to make any person feel humble. It also serves as a good reminder that we need to take care of the planet and of the many ecosystems that support countless forms of life. In this post are 3 pictures of Blue Whales that I took yesterday & last weekend near the Channel Islands, off the coast of Santa Barbara, CA. Blue Whales are endangered animals and were almost hunted to extinction during the last century. Today, the population estimate is about 8,000. Interesting fact: our world's largest animal survives by eating one of the smallest...krill. Krill is a small shrimp-like creature that the Blue Whales dive to depths of 700+ feet to feed on. To feed, the whales open their large mouth, ingest large amounts of krill, close their mouth, then push their tongue against the roof of the mouth to filter water out of their throat grooves. The krill then stay behind and get caught in the baleen plates. Blue whales are rorqual whales, meaning they have throat grooves and they are also baleen whales, meaning they have no teeth, but rather plates of baleen hanging from the roof of their mouth. Baleen is made of keratin, the same material that our nails and the hoofs of a horse are made from. The baleen plates of a Blue Whale can reach up to 40 inches long! In terms of overall size, today's Blue Whales are about 80-90 feet long, but in the pre-hunting days, they reached up to 110-120 feet in length. To see the by-product of a Blue Whale's krill diet, take a look at the following picture...yes, that's whale poop. The whales can't digest the small shells that encase the krill, so it comes out the other end. The red color comes from the red shell of the krill. We came across these ocean droppings minutes after the Blue Whale dove down for another bite to eat. I've also seen pictures of big red clouds in the water. If you ever come across such a cloud and know that you are in Blue-Whale territory, stay put and wait about 10 minutes to see if the whale surfaces anywhere within about a 1/2 mile radius of your boat. You just may get lucky and become one of the few people who has ever seen a Blue Whale firsthand. Visit the OceanSpot channel on YouTube to see some Blue Whale videos and videos of other ocean life.

19th Century Weapon Found in Whale
The AP reported an interesting story recently...a 19th century weapon was found in a whale that was hunted off the coast of Alaska in May 2007. It is believed that the weapon was shot at the whale in the late 1800's, and the whales estimated age is between 115 years and 130 years old. It was a Bowhead whale and some reports indicate that Bowhead whales can live to be 200+ years old...pretty amazing. The whale probably had more life to live, but it was hunted as part of a native whale hunt. The whale was about 49 feet long and was male. The weapon was lodged in a bone between its neck and its shoulder blade. The type of weapon is an exploding device. Once it is shot into the whale, it explodes and is supposed to kill the whale. Often, as in this case, the weapon does not kill the whale, or does not kill the whale instantly, causing a slow and painful death. This whale escaped death the first time many decades ago, but not the second. These explosive devices are still used today and are often viewed as inhumane...it's easy to see why. Here is a picture of the weapon that was recovered from the whale (left), along with an in-tact weapon (middle) and a ruler (right). (The photo in this post is from the AP and appeared in a story on USA Today's web site.)

Recycle Your Plastic Bags...Or Better Yet, Use Cloth
It's not yet posted on their web site, but the July 2007 print version of the "Southern Sierran" from the Angeles Chapter of the Sierra Club, has a story about the number of plastic bags that humans use every year and the damage they are causing to the environment. Did you know that Californians alone use over 19 billion (yes, billion) plastic grocery bags every year? Think of your last visit to the beach or a hiking trail...there's a good chance that you saw a plastic bag sitting around. Not only are the bags a big problem in our landfills (according to the article, CA's plastic bags account for 147,038 tons of waste/year), but they also pose a severe threat to wildlife, especially marine life. When plastic bags, large or small, end up in the ocean, they can often be mistaken for food. A white or transparent bag can easily be mistaken for a jellyfish or a squid. When an animal ingests the plastic, death will be the likely result. The article says that the U.S. EPA estimates that "marine debris has had a negative impact on at least 267 species around the world." It also mentions the juvenile minke whale that was found dead on the shores of France in 2002. About two pounds of plastic packaging and plastic grocery bags were found in its stomach, which researchers believe were the cause of its death. We can all do our part to help this problem by taking our plastic bags back to the grocery store for recycling, or by using re-usable bags and not taking the plastic bags in the first place. And next time you see plastic of any sort when you're out enjoying nature, especially at the beach, take a moment to pick it up and dispose of it properly...it just may save the life of the marine wildlife in the area.

Delta & Dawn...Back to Sea?
It sounds as if the humpback whale mother and calf who strayed from the Pacific Ocean to the Port of Sacramento found their way back to the ocean a couple of weeks ago. Let's hope their wounds are healing and that they're back on track with their proper migration pattern, probably heading to Alaska to feed. We heard a radio reporter wondering what the whales were eating while they were inland; he was worried that they might starve to death. If anyone else was concerned about this, it was probably not the most urgent issue at hand because the calf was surviving on its mother's milk and the mother often goes months without eating after giving birth and migrating back to summer feeding grounds...likely near Alaska. During migration, they usually don't eat, but once they arrive in the rich feeding grounds up north, they will eat and eat for a few months and will store up large reserves of blubber that allow them to survive without eating for long periods of time.

Sharks are in Trouble
There's a brief article in the May-June 2007 issue of Audobon Magazine about the horrific practice of shark-finning. Nearly 73 million (yes, million) sharks are killed each year worldwide, many of them only for their fins. After being caught, fisherman slice the dorsal fins off of live sharks, then toss the sharks back in the ocean to die a slow and miserable death. Keeping only the fins leaves the fisherman more room on their boats. There is a high demand for shark-fin soup in Asia and a growing appetite for it in the United States, as well. Many shark species are now considered "critically endangered," "endangered," "vulnerable," according to the International Union for Conservation of Nature and National Resources (IUCN). See their "Red List of Threatened Species." You can read the Audubon article (NOTE: there's an unpleasant photo there) and can do your part by avoiding shark-fin soup in restaurants and by expressing your concerns to any restaurants who offer it on their menus.

Humpback Mother & Calf Swim to Sacramento
Have you been following the story of the Humpback whale mother & calf (now named Delta & Dawn) who took a wrong turn in San Francisco and swam up a shipping channel all the way to the Port of Sacramento? They ended up about 90 miles inland and authorities have been trying a variety of methods to encourage them to turn around and head back to sea.

View Larger Map
It appears that they have each sustained injuries from either a boat propellor or rudder. Getting back to the salty water of the ocean should help the wounds heal, but the whales are taking their time getting home. They have turned around and are headed west, but have been reluctant to swim under the Rio Vista Bridge. On the map above, note the blue dot near Sacramento to see how far inland the whales swam. Let's hope they find their way back to the ocean soon.

Does Military Sonar Sidetrack Whales?
There's an interesting video from National Geographic. It discusses the impact of military sonar on the Killer Whales in Puget Sound. Debate continues on the impact of underwater sonar on marine mammals who use echolocation as a means of navigation, communication, and foraging for food. It seems hard to believe that man-made noise is not having a negative impact on these mammals. What do you think?
