From the genus Magnapinna, the Bigfin Squid's long tentacles can grow up to four and six meteres (13-29 feet). Their purpose? Scientists speculate that they run them along the sea floor to snatch prey.

two thing I didn’t know  (and probably you too) about the giant isopod (Bathynomus sp) swims very well, and digs burrow.

A important detail is the two red dots are from lasers mounted on the ROV and are 10 cm apart (this techique is called photogrammetry)

Just a reminder:the natural diet of these birds is BONES. Not just bone marrow; actual bone shards. They pick up huge freaking bones from carcasses and drop them onto rocks until they get spiky pieces and then they swallow them. Their stomach acid dissolves bone.

look me in the eye and tell me that’s not a fucking dragon

And they aren’t naturally red like that. That’s self-applied makeup. They find the reddest earth they can to work into their feathers as a status symbol.

And they don’t scavenge other parts of carcases, just the bones. 85-90% of their diet is exclusively bone. Hence why it’s only a myth that these birds would just pick up whole lambs and carry them off. It’s not true, but in German they’re still called Lämmergeier as a result.

So metal

A rare pink hippo bathes in waters in South Luangwa, Zambia, Africa, while surrounded by dozens of his normal-coloured cousins. Contrary to popular belief, the hippo is not an albino but is actually leucistic, a condition where the pigmentation of cells in an animal fail to develop properly. Leucism can often affect an animals chances of survival as it makes them visible to predators as well as being at risk of sunburn.

The gum leaf skeletoniser(Uraba lugens, sometimes charmingly called the Mad Hatterpillar) can be found in Australia and New Zealand, where it is regarded as a pest due to the damage groups can do to eucalyptus trees. As the caterpillar grows it becomes limited by the size of its exoskeleton and to continue growing, it needs to shed its current “skin” for a new, bigger one. Whereas other species may discard their old exoskeletons or eat them, gum leaf skeletonisers keep their old heads and form a large hat out of them. As a general rule, the taller the hat the older the caterpillar.

ZOOLOGGER: Mollusc Grows Hardest Teeth in the World

Species: Chaetopleura apiculata
Habitat: The waters of the Gulf of Mexico and the north-west Atlantic

For more than 400 million years chitons – marauding marine molluscs – have roamed the seas, munching on algae-encrusted rocks with their glittering black, metallic teeth. Chitons roam courtesy of a single, broad muscular foot. They have a shell, made of eight plates, and some species live up to 20 years.

But it’s the teeth we’re interested in. The teeth are the chiton’s answer to Wolverine’s adamantium skeleton. But these are no fiction. They are the real thing, made out of magnetite, the hardest material made by a living organism.

Lyle Gordon, a bioengineer at Northwestern University in Evanston, Illinois, has come a step closer in understanding just how the humble mollusc grows them…

Photos of Alitta virens by Alexander Semenov. Don’t let the pretty colors fool you, these sandworms are plenty scary. They can get quite big (sometimes exceeding four feet)  and they occasionally bite humans. They just might be the nastiest thing in pastel since James Spader in an 80’s movie.
