If it’s against the law to abuse cats & dogs (and children), then that shows humans understand what’s right & wrong. Brother & sister dolphins in prisons…more abuse. It’s easy – set them free.
Thirty metres long, blue whales are immense…and they travel great distances. Except for these…they (far as any people know) hang around Sri Lanka & don’t appear to go anywhere. With only 10K left worldwide, they are on most countries’ endangered list, and their recovery from whale hunting is going slowly.
This video is an exploration of that, and some of the obstacles to studying them – some in science, some in the environment, and some in the way our society does things. Amazing video & amazing photos of amazing friends in the water….
Then there’s more – here’s a story you have to hear on NPR (here’s the audio):
Blue whales are updating their playlist, according to new research on the huge mammals.
It’s not quite West Side Story, but male blue whales use songs to warn away other males and attract females. It’s a pulsing sound, more like a large piece of machinery than the Jets and the Sharks.
But that song has been changing.
John Hildebrand of the Scripps Institution of Oceanography studies whale sounds and says he’s been hearing something new lately.
“They’ve been shifting the frequency. They’ve been shifting the pitch to be lower each year. And that shift in pitch has resulted in song that is now about 30 percent lower than it was in the 1960s,” he says. He says the change is happening in blue whale colonies all over the world.
Hildebrand believes the change is tied to the elimination of blue whale hunting. Before hunting was banned in 1966, the numbers of blue whales were dangerously low.
“Worldwide in the early ’60s, there probably would have been a few thousand,” he says.
Those low numbers meant there were few females available to hear a male’s come-hither song. For males in that situation, “there’s a push to have the sound go to higher frequency so that more of the girls can hear it.”
In other words, the guys had to shout to be heard. But now that blue whales are more numerous, Hildebrand thinks the males have gone back to singing bass because it makes them sound bigger and more attractive to females. He says males of many species use lower tones to attract mates.
“In fact, human females, if you put some headphones on and play a bunch of male voices and you tell them to pick out the sexy voice, do they pick the weak little voice or do they pick the big booming voice?” Hildebrand says. “You know the answer.”
No one disputes the finding that blue whale songs have gone down in pitch. But Hildebrand’s theory of why it’s happened has raised some eyebrows.
“It’s a great anthropomorphism to suggest that the whales have thought this through,” says Richard Ellis, a whale expert at New York’s Natural History Museum.
“I really don’t think that the whales — for all their big brains and everything else — I really don’t think the whales think about this,” Ellis says.
Still, Hildebrand says, if a lower tone becomes an advantage to some males, it will be copied by others.
How do they know that Granny, the killer whale in J pod in the San Juan Islands who is estimated to be 103 years old is that old? Here is Monika’s tribute post to her when she turned 100 that explains that (which is cool) as well as offering insight why we all love her so….thanks, Monika!
From my friend Carol:
In recent years years, bottle-nose dolphins were documented riding humpback whales in Hawaiian waters. The dolphins actually slide down the backs of the whales into the water like a makeshift “slip and slide.”
Scientists believe it is just a game between the two species, because neither of them displays aggressive or distressed behavior toward the other. It seems to be play-time that they both genuinely enjoy. When the dolphins are riding on the whales’ backs, the whales will sometimes go up to the surface and lift the dolphins into the air. The interactions are rare or at least, very difficult to capture on camera.
More about it on YouTube:
What do you do when a friend asks for help? Easy answer.
Keller Laros was diving when a dolphin came & asked for help. I honestly believe this little video will change your day.
Thanks, Keller & Martina (who shot the footage)!
Human/killer whale attacks are rare, which prompts this expert in New Zealand to suggest this event was unfortunate, but more of an accident – here’s more:
An expert on marine animals is skeptical about reports of an orca grabbing a free diver’s catch bag and dragging him underwater until the rope became free.
Whale rescue co-founder, Far North-based Jo Halliday said it was not unheard of for such an incident to occur but she doubted it was a case of “whale attacks man”.
Levi Gavin, who was diving for kina and crayfish two weeks ago at Horahora estuary, on the coast east of Whangarei, said he was dragged beneath the water for about 40 seconds after the orca grabbed the catch bag tied to his right arm.
Mr Gavin described being down to his “last breath” in a death spiral, and trying to relax to conserve his breath as the huge creature dragged him deeper and deeper.
I love to read Monika Wieland‘s take on the way things work in the natural world…she writes so well & you already know I’m a fan of her pictures!
Here’s her report from Baja, with her first day on the water, with her observations & photos.
So they’re doing it in the cold seas of Russia. According to Erich Hoyt:
Four more orcas have now been confirmed to have been captured in Russian waters for ocean amusement parks and aquariums. That makes seven total captured in the past 2+ months in two separate captures in the Sea of Okhotsk—the massive far eastern inland sea of Russia, lying due north of Japan. Having spent time with these wild, beautiful orcas, I feel personally, as well as professionally, depressed about these developments.
The first 2013 capture happened in mid-August. The three orcas, or killer whales, were taken by a Russian catching team, the same team that caught a female orca in the same general area at the same time last year. For the past year, that young female — someone named her Narnia and the name stuck — has been swimming alone in a tiny makeshift pen near Nakhodka (Vladivostok area), awaiting her fate. The rumors have consistently pointed to her eventual transfer to Moscow.
There is no known resident pod of orcas around Hawaii, which makes it that much more exciting – and that much more rare – when they are seen.
Here’s more from Pete Thomas Outdoors about last week’s sighting, and what it means.
Just what you want to hear. And yeah, more than a coincidence.
On Tuesday, killer whales came close to a ferry from Seattle as it approached Bainbridge Island. The killer whales surrounded the ferry and splashed in the water.
By coincidence, on board the ferry were officials from The Burke Museum in Seattle who were returning tribal artifacts to the new Suquamish Museum. The artifacts were dug up nearly 60 years ago from the site of the Old Man House, the winter village for the Suquamish tribe and home of Chief Seattle.
Also on board was Suquamish Chairman Leonard Forsman. He believes the appearance of the orcas was no coincidence. He believes they were welcoming the artifacts home to the reservation.
If dolphins & dogs can get along….
You’ve kissed people – did you ever see anyone jump like this, afterwards?

When freediver Chris Coates was swimming off the coast of Africa, he had seen humpbacks all day….but this one came close & thumped him with its pectoral fin. You can see his amazing video & the rest of the story here – check it out!
Ever since I met Captain Charles Moore a few years ago (he came to San Juan Island for a rousing talk), I’ve had plastics on the brain. If you haven’t seen his here’s-everything-in-a-nutshell TED talk, check it here.
The amount of plastic in the world’s oceans is staggering, and it makes its way into the animals who live there. I’m happy to see that people like Angela Sun are making documentaries about this (here’s her trailer for her film, Plastic Paradise):
This is not isolated to any one part of the world – it is everywhere. The whale in the photo above died because it was filled with plastic waste, and there’s a lesson in its death about the direction it – and we – as a species are headed.
Carl Safina came to San Juan Island in Washington State to see what’s happening with the killer whales, and to hang out with the Center for Whale Research’s Ken Balcomb.
The state of the environment for the orcas: short on food, and decreasing numbers in the resident pods. It doesn’t help that the Navy does sonar testing in these waters, either.
