Helicocranchia pfefferi, the banded piglet squid, is a small squid of the genus Helicocranchia. Adults of this species are mesopelaegic.

Physical characteristics[edit]

The average size of adult H. pfefferi is 100 mm (3.9 in) 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.[citation needed] 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.

Habitat[edit]

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 exhibit a diel vertical migration pattern.[3]
