Sharpear enope squid, Ancistrocheiridae
Ancistrocheirus lesueurii, the sharpear enope squid, is the only species in the genus Ancistrocheirus and family Ancistrocheiridae. With a mantle length of 25 cm, this moderately sized squid may be found throughout the tropical and subtropical oceans. They tend to be found at mesopelagic depths (200–1000 m down).
Although only one species is recognized, some have suggested more than one species may exist due to differences in the paralarval morphology. Paralarva is the first free-living stage for cephalopods.
The buccal crown of the sharpear enope squid is heavily pigmented. The squid has no vesicles. There are hooks on all its arms. The suckers are absent from its manus and the squid's dactylus is reduced.
They are eaten by the sperm whale in Southeast Asia and Galapagos waters
