Piglet squid (Helicocranchia sp.) gets its nickname for its small round body, wiggling tail, and siphon that looks like the nose of a pig. Credit: MBARI researchers 900 meters (2,950 feet) underwater off the Monterey Bay.

This squid has always got a smile on its face! The skin pigmentation of this little deep water squid gives it a huge grin, while the tentacles seem to form a mass of curly 'hair', combining to give it an almost cartoon appearance.

The Piglet squid, Helicocranchia pfefferi, is roughly the size of a small avocado, and is common in the deep water of virtually all oceans, living at depths of around 100m/320ft.

Its common name comes from its habit of filling up with water and the unique location of its syphon, with a wild-looking tuft of eight arms and two tentacles.
