Here's an incredibly cool video showing the prow of a massive ice breaking ship as it plows through Antarctica's Ross Sea. The footage is sped up, to pack two months of travel into five minutes. But, unlike a lot of time-lapse videos, this one also has a really informative audio track, in which marine scientist Cassandra Brooks waxes poetic about the many different kinds of ice and explains why she and her team were out there, breaking through the stuff, to begin with.
Bonus: At the end, you get to see the absolute adorableness that is penguins on high-speed fast forward.
Please enjoy this very serious, scientific Tumblr that posts exactly what it promises — pictures of the strange and fantastic creatures that live deep in the ocean ... with googly eyes photoshopped onto their bodies.
The specimen above is an animal known as the pigbutt worm. Yes, seriously. With the googly eyes in place, you can't quite get a full understanding of how weird looking this animal is, so please be sure to check out the "before" photo, as well.
The site is maintained by a deep sea ecologist (he's anonymous, but I've verified that this is true). So you can trust the information provided here. For instance, when readers ask how the heck a pigbutt worm counts as a worm:
The pigbutt worm, Chaetopterus pugaporcinus, is a very weird looking worm, for sure. All Annelid worms are segmented, and the pigbutt is no exception. If you look at an ordinary earthworm, you can see those segments, but in Chaetopterus pugaporcinus, the middle segments are super inflated compared to the rest of its body. The rear segments are visible in the area that looks like the anus on a mammal’s buttocks (although others have noted that this section of the pigbutt worm looks more like a disembodied vulva than a floating buttock).
Ambergris is often referred to as "whale vomit", but that's not really correct. A more accurate analogy would be to say that ambergris is like the whale equivalent of a hairball. It's produced in the whale digestive tract, possibly to protect intestines from the sharp, pointy beaks of squid — you'll often find squid beaks embedded in the stuff. Most of it gets pooped out. But the big chunks of ambergris have to exit the other direction. In the human world, these lumps — which have the consistency of soft rock or thickly packed potting soil — are famous because we use them to make things like perfume. The ambergris washes up on beaches, people collect it, and sell it to make cosmetics.
That news made me realize that I'd never actually seen a picture of ambergris before, so I went hunting around to see what the stuff looked like. That's a photo of a lump of ambergris, above. But it's not really indicative of what ambergris looks like all the time. In fact, as far as I can tell, the stuff comes in a wide variety of shapes and colors — ranging from stuff that looks like small brown pebbles to yellow-green globs covered in bubbly nodules. The diversity is worth perusing. This website, for a company that buys and sells ambergris, has several nice photos. And Google image search turned up a plethora of pics that really capture how different one lump of ambergris can be from another.
When ocean scientist Andrew Thaler found an old, outdated water level gauge, he found a way to give it new life — turning it into a tool to measure public interest in sea level rise. Instead of tracking water, the Sea Leveler tracks how much people are talking about water on Twitter.
It's a small squid world, after all. A recent study shows that giant squid from all around the globe have remarkably low levels of genetic diversity — essentially, writes Tina Hesman Saey, they're all more closely related than scientists previously thought. Giant squid, as it turns out, are a single species, traveling, living, and breeding all around the planet. — Maggie
But looks can be misleading. What's actually going on here is external fertilization — that is to say, procreation without any of the potentially awkward penetration. Male lobsters produce spermatophores, packets of sperm, which they attach to the female's sternum. That's what you see happening here, according to the Sanctuary. Later, the female will use that sperm to fertilize her eggs.
Say you're a marine biologist and you want to study the little bitty creatures of the sea — shrimps and worms and things like that. How do you go about capturing them?
Why, with an underwater vacuum, of course.
At the PNAS First Look blog, David Harris writes that this "SCUBA-tank powered vacuum, called an “airlift,” inhales shrimp, sand fleas, marine worms, and 'things that would swim away if they had the chance.'"
"The earliest sawfishes likely arose in the shallow Tethys Sea, that ocean surrounded by the ancient continents of Godwanda and Laurasia, during the Cretaceous period at least 60 million years ago," writes Dr. M. at Deep Sea News.
These "sole survivors of an ancient bloodline" now number only seven species which roam the muddy bottoms of coastal areas, bays and estuaries.
All sawfishes can move easily between fresh and saltwater and often venture deep upstream into rivers. The sawfish lifestyle puts this both their size and saw near humans. All seven species are considered critically endangered by the IUCN. As much as we have impacted them, sawfish have also greatly influenced our culture.
And now, they're one of the most threatened species on our planet. Thanks, humans!
Jason Isley is an underwater photographer, which means that the strange and wonderful creatures you and I go ga-ga over are really just part of a workaday routine for him. This is a fact which has gotten him into fights on the Internet ...
I made a comment online recently that I was growing tired of nudibranches and was immediately bombarded with abuse and comments from ‘nudi-lovers’. Allow me to clarify: It’s not that I actually dislike the little flamboyant slugs, but once you have shot a few thousand images of nudies and other common macro life, I was running out of ways to maintain my passion for photographing them. I’ve shot them from countless angles and under a variety of lighting configurations. I know there are now lots of different techniques and gadgets to spice things up, like snoots, external macro diopters, and bugeye lenses, but for me, I really wanted to do something entirely different.
The cookiecutter shark is one of those animals that kind of makes you believe nature just likes to mess with us. Instead of killing the things it eats, a cookiecutter shark just takes a bite — leaving a neat, tidy hemispherical divot. As marine biologist Yannis Papastamatiou told reporter Douglas Main, it would be more accurate to call the cookiecutter an "ice cream scoop shark". Despite only being about 20 inches long, the cookiecutter shark will try its luck on a wide variety of prey, including animals much larger than itself. It's been known to bite great white sharks, for instance. And there is one report of a cookiecutter biting a human, although that risk is probably not something you should bother losing sleep over. — Maggie
