Bathyteuthis is the singular genus of squid in the family Bathyteuthidae, encompassing three species.
Histioteuthis is a genus of squid in the family Histioteuthidae. It goes by the common name cock-eyed squid, because in all species the right eye is normal-sized, round, blue and sunken; whereas the left eye is at least twice the diameter of the right eye, tubular, yellow-green, faces upward, and bulges out of the head.
Histioteuthidae is a family of Oegopsid squid. The family was previously considered to be monotypic but the World Register of Marine Species assigns two genera to this family.
Histioteuthis bonnellii, the umbrella squid, is a species of cock-eyed squid belonging to the family Histioteuthidae.
Histioteuthis reversa, commonly known as the reverse jewel squid or the elongate jewel squid, is a species of cock-eyed squid, so called because the eyes are dissimilar. It occurs at moderate depths in the Atlantic Ocean and the Mediterranean Sea. It is also known from the Indian Ocean.
Stigmatoteuthis hoylei, commonly called the flowervase jewel squid, is a species of cock-eyed squid. It is native to tropical and subtropical waters of the Indian and Pacific Oceans. It grows to 20 cm (7.9 in) in mantle length. The eyes of this species are highly dimorphic.
Histioteuthis heteropsis, known as the strawberry squid, is a species of small cock-eyed squid. The scientific nomenclature of these squid stems from their set of differently sized eyes, one being small and blue and the other being large and yellow. It is thought that the large eye is used to see objects against dim light, while the smaller eye is more able to view bioluminescent light sources. The squid's vernacular name arose due to its rich red skin pigmentation and the presence of photophores along its body, making it appear like a strawberry with seeds.
Histioteuthis meleagroteuthis is a species of small to medium squids that have a dark, wine-red skin pigment. Females at maturity average at 114 mm (4.5 in) in length, while males at maturity average at 65 to 102 mm in length. This species is characterized by tubercles, photophores, and asymmetric features. This species can be found in circumglobal, mesopelagic waters.
