Ancistrocheirus lesueurii, the sharpear enope squid, is the only species in the genus Ancistrocheirus and family Ancistrocheiridae. With a mantle length of 25 cm (9.8 in), this moderately sized squid may be found throughout the tropical and subtropical oceans. They tend to be found at mesopelagic depths (200–1,000 m (660–3,280 ft) 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.
