Vampyroteuthis.
Fascinating animal, did you know it is the only surviving member of the vampyromorphs? They were a widespread cephalopod group with many differing forms back in the Jurassic and Cretaceous. Many of these ancient forms had two pairs of fins, a trace of this can be seen in the Vampire which grows two pairs, the first pair being absorbed back into the body shortly after hatching.
This bizarre animal is neither a squid or an octopus but probably had a common ancestor with those groups back in the late Devonian at some date approximately around 360 million years ago. That's why many people refer to it as a living fossil.
An incredible beast indeed.
