In 1936, the Tasmanian tiger (Thylacinus cynocephalus) was declared to be extinct. Yet in the last three years, there have been eight reported sightings according to Tasmania's Department of Primary Industries, Parks, Water and Environment. I hope it's true. From CNN:

While stories abound that some continue to live in the remote wilds of Tasmania, an island state off Australia's south coast, there has been no hard evidence to support this -- only claims of sightings, like the ones newly released.

One report last February said that two people, visiting Tasmania from Australia, were driving when an animal with a stiff tail and striped back walked onto the road.

The animal "turned and looked at the vehicle a couple of times" and "was in clear view for 12-15 seconds," the report read. Both people in the car "are 100% certain that the animal they saw was a thylacine."

Another report filed the same month described a striped "cat-like creature" moving through the mist in the distance.

The blob has no mouth, but I must scream.

To be fair, it doesn't a stomach, or eyes, or feet, or anything resembling a brain, either (at least as far as modern science would define it). It's not technically a fungus, or an animal, or a planet. It is, quite simply, an incomprehensibly bizarre yellow slime mold that's also alive, and at least somewhat-sentient. Even its official scientific classification, physarum polycephalum, literally translates to "many-headed slime."

And now it's held captive and displayed at the Zoo de Paris, starting October 19.

Did I mention that this blob has some kind of intelligence, or at least the ability to remember things, and absorb knowledge from other slime mold blobs that it consumes? And that it's capable of moving independently, squishing along at a limbless rate of about 1.6 inches per hour? It also has 720 different sex organs, and will heal in two minutes if you cut it in half.

It also, apparently, loves the taste of oatmeal, as well as Acacia trees, oak bark, and chestnut bark. So um, at least it's probably not going to eat us when it ultimately escapes and seeks its revenge for being caged and mocked by us lowly humans? Maybe. If we're lucky.

From EuroNews:

"The 'blob' is a living being that is [one] of nature's mysteries. We don't really know what it is," director of the Paris Museum of Natural History, Bruno David, said, adding that it lives and grows in damp forest undergrowth away from the light.

Sara Varon is co-creator, with Cecil Castellucci, of Odd Duck, the 2013 outstanding kids' picture book, and her latest solo venture, New Shoes is a brilliant reprisal of the themes from Odd Duck: camaraderie among eccentric animals, charming small-town life, fascinating technical details, humor, and beautiful, engaging illustrations.

"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!

Three live cams captured this polar bear family behavior rarely caught on camera.

Ed Yong writes about the Chinese soft-shelled turtle: "Looks like someone glued the snout of a pig onto the face of a fish, with the texture of a scrotum for good measure. But its bizarre appearance pales in comparison to an even more bizarre, and newly discovered, habit: it urinates through its mouth." Read the rest

From a public perspective, biology in the oceans, like biology on the land, tends to favor the charismatic megafauna. Stop by your local aquarium and you'll find masses huddled around the seal pool or the shark tank. People will even attempt to interact with the octopodes. Meanwhile, smaller creatures sit on the sidelines. Crabs, starfish, and ray-like skates have some admirers at the touch tanks. But in the world of small things, they're actually quite large. The ocean is full of even tinier organisms—worms and snails, small shelled animals and even stationary colonies of life that look like rocks or lumps of sand.

The ocean is an amazing place, and Bill Grossman can tell you about the things that live there—large, small, or tiny. Grossman is specimen collector for the Marine Biological Laboratory. Essentially, he's part of a system of support staff for scientists. When researchers at MBL need sea creatures to study, it's people like Grossman who go out on the water and find them.

Back in May, I got to take a short trip aboard the R/V Gemma, MBL's specimen collection boat. The videos I brought back can teach you some amazing things about animals you thought you knew well, and introduce you to creatures you probably never noticed before. Read the rest

Sometimes, I get so jealous of British television. Apparently, there's a whole series over there called Inside Nature's Giants. It's basically a zoology dissection show, where scientists break down large, exotic animals in ways that help teach viewers about evolution, biology, and the science of animal locomotion.

John Hutchinson is an American zoologist who works as a professor of evolutionary biomechanics in the UK. He's one of the scientists who works behind the scenes on Inside Nature's Giants. He also blogs at What's in John's Freezer?. It's a great title and it gets right to the point: Hutchinson has a job that is centered around the frozen carcasses of all manner of strange (and usually rather large) creatures. His research is all about the evolution and mechanics of motion. He studies living animals, both through dissection and 3D modeling, and he tries to use that data to better understand how extinct animals—including dinosaurs—might have moved around.

It's fascinating stuff. And the photos are nigh-on mind blowing. Right now, at John Hutchinson's blog, you can see a collection of shots from dissections and CT scans done for Inside Nature's Giants—including the dissection of an elephant.

Because I know that some of you are delicate and it is almost lunchtime, I've opted to not post my favorite photo from that dissection on the main page. But you should check it out below the cut. Read the rest
