Piglet Squid

Could it be an ancient relative?

-Joan

Here’s some info from the Cabrillo Marine Aquarium who found this thing:

Piglet Squid, Helicocranchia pfefferi

This funny looking squid is about the size of a small avocado and can be found most commonly in the deepwater (greater than 100 m or 320 ft) of virtually all oceans. Its habit of filling up with water and the funny location of its siphone with a wild-looking ‘tuft’ of eight arms and two tentacles had prompted scientists to name it the piglet squid.

The body is almost totally clear revealing a dark mass that is the internal organs and barely visible, feather-like gills. Pigment organs dot the surface of the skin. In the picture a row of these ‘chromatophores’ provide a smile-like look. There are two small finst at the opposite end of the body from the head. Very little known of its biology. It has been observed from submersibles in the head down oriengation, but no one is sure why. It is a sluggish swimmer with ammonium ions in its body fluid that help keep it bouyant. A large light producing organ (photophore) is located beneath each of its large eyes.
