Whale Wednesday

blue whale dorsal fin

Ever wonder how you measure up (literally) compared to a blue whale? It is easy to throw around things like “largest mammal” and “gentle giant of the deep” but it can be hard to imagine just how large these animals are. Visit the Whale and Dolphin Conservation Society website for a chance to see just how mammoth these creatures are. A life size image of a blue whale scrolls across your screen. The first image that loads is of an eye the size of your palm. I kid you not -- I gasped out loud. Encountering animals in their natural habitats is far more awe-inspiring than flash versions on my computer screen, but I’ll take the virtual version for now.

Whale Wednesday

right whales

Good news for this whale Wednesday: According to new research presented, interestingly, at the Acoustical Society of America, the distinctive calls of North Atlantic right whales have been detected in a former whaling ground off the southeastern tip of Greenland. Right whales in the area were presumed extinct due to hunting in the late 19th century, and in the past 50 years, only two whales have been spotted in the area. Curious what the right whale sounds like? Listen to the "upcall," "gunshot" and "scream" the scientists might have heard.

Whale Wednesday

keiko free willy orca

Welcome to Whale Wednesday, the first ever hump(back) day feature devoted to cetaceans. I'm taking a cue from Oceans4Ever, the masters of alliterative weekly features, like Make a Difference Monday and Freaky Fish Friday. Hopefully this will become a semi-regular feature -- what's not to love about whales, after all? Today, three scintillating stories about cetaceans: 1. The Seattle Times reports on the first scientific review of the effort to reintegrate Keiko, the "Free Willy" orca, into the wild. The paper, which appears in the journal Marine Mammal Science, shows that while Keiko wasn't accepted by other orcas and had to be fed frozen fish until he died in 2003, he lived a longer life span than any other captive male orca. Turns out Willy's freedom was only possible on screen -- having been captured at the age of 2, he had been held in captivity too long to make it on his own.

The Unicorns of the Sea

During recess in grade school, I used to tie a sweater around my waist for a tail, use my pointer finger as a horn, and gallop around the playground, neighing and tossing about my mane. Yes, I was THAT girl who pretended she was a unicorn. I’ve since changed and fulfilled my interest in fantasy creatures by reading science fiction books and watching movies, but I don’t have to travel to the land of make-believe to learn about mysterious animals with impressive tusks. I just have to travel to the ice clogged inlets of Arctic Greenland, via this month's issue of Smithsonian Magazine. Little is known about these “unicorns of the sea”- biologist and narwhal specialist Kristin Laidre speculates that “we probably know a lot more about the brains of grasshoppers than we do about narwhals." Check out the fascinating article for a history of the narwhal, how Laidre (sometimes) successfully tags narwhals, and why any of this is important.

Sailors Detour for Whales

volvo ocean race

You may have read about the around-the-world Volvo Ocean Race on our OCYC blog, but here's a first for the race: as the NYT reported, the seven remaining yachts had to make a detour to go around a whale sanctuary near Boston this weekend. The boats, which can reach 30 mph, sailed around the Stellwagen Bank National Marine Sanctuary and the North Atlantic right whales that are feeding in the area. Due to the boats' speed, a collision with a whale can be disastrous for both parties -- the animal may be killed and crew members could be thrown into rigging (that's the sailing apparatus, for all you non-sailors). Marine mammal collisions are increasingly a problem. Several sailors in the recent Vendée Globe race sustained severe damage to their boats after hitting what they believed were marine mammals. And one sailor in the Artemis trans-Atlantic race last May had to abandon his boat after he reported striking a large sea mammal.

Blue Whales at NatGeo

I've been infatuated with blue whales since I was a child (who isn't?), so I was thrilled to watch Flip Nicklin, one of the preeminent whale photographers in the world, speak last night at National Geographic. The 61-year-old Nicklin was introduced to whales as a kid. He began by telling how his father, also a diver and underwater photographer, once rode a blue whale that was caught in a gill net (he later set it free, don't worry.) Since, then he's been traveling around the world, from Patagonia to Sri Lanka, in search of the largest animal ever to have lived on Earth. And sometimes they're not very easy to find. "I'm fairly deaf," Nicklin said, "so I'm glad the whales are big." Big is an understatement -- the modern-day dinosaurs can be up to 100 feet long and weigh 200 tons, and their hearts can weigh as much as an SUV. They eat krill almost exclusively, and sometimes up to four tons a day. On a recent expedition, he spent more than three weeks at sea, and saw only one blue whale for a total of about 15 minutes. He got five usable photographs, all taken during the same minute. "They're good at playing hide-and-seek," he joked. But sometimes they are quite literally under his nose. In one video he showed, a blue whale eyed him curiously -- from less than five feet away. And most recently, he traveled to Baja, where he saw more than 20 blue whales.

The Scanner

This week in ocean news, ...A 72 million-year-old sea turtle fossil -- the oldest on record -- was discovered in Mexico. ...A council plans to vote in June on protecting the sea floor from Florida to North Carolina from bottom trawls, bottom longlines and other destructive fishing gear. The 23,000 square miles is thought to encompass the largest deepwater reef system in the world. ...Almost 200 pilot whales and bottlenose dolphins were stranded on a beach in Tasmania, the fourth beaching incident there in recent months. ...The fisher poets (no relation to yours truly) had their annual gathering in Oregon. ...Scientists discovered a carnivorous sea squirt that looks like a desk lamp. ...As the OCYC notes, David de Rothschild is leading a project to build a 60-foot catamaran out of plastic bottles, called Plastiki, which he will sail from California to Australia. ...A Bengal tiger cub and a dolphin made friends. The next Disney Pixar movie, anyone?

Good Tidings for Right Whales

right whale and calf

CNN has a terrific story about this year's crop of right whales, among the most endangered animals on earth. Just an estimated 400 of these massive creatures still live off the U.S. Atlantic coast, and they sometimes get struck by ships or tangled in lobster trap lines. But there seems to be good news: This year's crop of right whale calves is the largest ever recorded, with at least 32 new whales spotted by a bevy of scientists in prop planes and volunteers at lookout points on beaches. It's really a great story, so head on over and check it out.

Dolphins, Whales Still Threatened By Fishing

On the heels of President Bush's creation of three vast marine national monuments in the Pacific comes some not-so-great news about the outgoing president's stewardship of the oceans. In a new report, the U.S. Government Accountability Office (my personal favorite of the federal agencies for its malfeasance-ferreting-out ways) has found that the National Marine Fisheries Service has failed to protect several marine mammal species, even though it's required by law. Under the Marine Mammal Protection Act, the federal government is required to reduce the number of marine mammals that are incidentally killed by commercial fishing activities. For example, the North Atlantic right whale can be caught in lobster trap lines; pilot whales can be trapped in longline gear used to catch tuna; and dolphins and porpoises can be ensnared in nets set to catch cod and salmon. The GAO found that the National Marine Fisheries Service has been unable to establish plans to protect 14 of the 30 marine mammals required by law due to a lack of funding and insufficient data.
