Lycoteuthidae

Family of squids

The Lycoteuthidae are a family of squid comprising three known genera. They are small muscular squid, characterised by a lack of hooks and by photophores present on the viscera, eyeballs and tentacles. They inhabit tropical and subtropical seas where the diel migrants stay down in the mesopelagic zone during the day and migrate to the surface to feed at night. Some species show strong sexual dimorphism.
