It’s called a coelacanth and until African fisherman began netting them recently, they were thought to have been extinct for more that 80 million years.
I have a friend who is inexplicably fascinated by Giant Squid (Freud would have a field day with that one) so I thought this might pique his interest. But cool as the Giant Squid may be (and no one’s doubting it), only the coelacanth can claim to be:
[…] the only living animals to have a fully functional intercranial joint, a division separating the ear and brain from the nasal organs and eye.
See, you learn things here.
