Helicocranchia is a genus of small glass squids from the family Cranchiidae, known as piglet squid. They are characterized by possessing a very large funnel and in having a pair of small paddle-like fins which are attached to a part of the gladius which sits above the muscular mantle. These squid undergo a slow descent starting near the surface as paralarvae moving down to lower mesopelagic depths as near-adults.[2]
The genus contains bioluminescent species.[3]
Species
There are three species of Helicocranchia:[1]
- Helicocranchia joubini (Voss, 1962)
- Helicocranchia papillata (Voss, 1960)
- Helicocranchia pfefferi Massy, 1907
