The Banded Piglet Squid (Helicocranchia pfefferi) is a small squid of the genus Helicocranchia. Adults of this species are mesopelaegic.
The average size of adult H. pfefferi is 100 mm in mantle length (ML). The body consists of a large funnel with small paddle-like fins. They have small tentacles above their eyes. The funnel does not have valves but contains a dorsal pad with three papillae as organs. Paddle-shaped fins are attached to a part of the gladius. H. pfefferi has a single ocular photophore and does not have photophores at its arm tips.
As paralarvae (<30 mm ML), they live near the surface of the oceans, between 100 m and 200 m deep. They descend to the mesopelagic zone as they mature, but do not exhibit a diel vertical migration pattern
These are some pretty cool looking, Squid. The face is very cool.
