    Teuthowenia are medium sized deep-sea cranchiids. There are three known species, with global distributions that do not overlap.

    Or if you would like more information, you can just PM me, or post here. These are the squid that I am looking at in NZ, so I know the odd fact about it.

    Here is a short clip of Teuthowenia megalops in what is known as the "cockatoo posture".

    I don't know D, they're not quite as pretty once they're preserved. I might be able to arrange something though...

    Just out of curiosity... what is this organ (object)? Is just the ink gland?

    Here, the same specimen shot from a different angle. I'm still working the internal anatomy out, but I'm pretty sure that's the ink sac.

    I remember seeing this in a book once, they called it a "glass squid" that inflates itself and inks into it's own body for camouflage

    Yeah, Teuthowenia (and many of the cranchiids) tend to make it into deep sea books. They seem quite photogenic. "Glass squid" is actually a common name given to the whole family, as many of them are do the behavior you mention.
