Ommastrephidae is a family of squid containing three subfamilies, 11 genera, and over 20 species. They are widely distributed globally and are extensively fished for food. One species, Todarodes pacificus, comprises around half of the world's cephalopod catch annually.
Liocranchia is a genus of glass squid from the family Cranchiidae. They are moderate-sized with a long, spindle-shaped mantle which tapers to a point at the rear and they can attain mantle lengths of 250 mm. The species in Liocranchia have a cosmopolitan distribution in tropical and subtropical oceans although it has been suggested that on especies, Liocranchia reinhardti is associated with land masses. In seas off Hawaii waters L. reinhardti undergoes vertical migrations while L. valdiviae occurs in deep water is sedentary. They are eaten by many oceanic predator species.
Metasepia pfefferi, also known as the flamboyant cuttlefish, is a species of cuttlefish occurring in tropical Indo-Pacific waters off northern Australia, southern New Guinea, as well as numerous islands of the Philippines, Indonesia and Malaysia. The flesh of this colorful cephalopod contains unique acids, making it unsuitable for consumption.
Sepiola atlantica, also known as the Atlantic bobtail, is a species of bobtail squid native to the northeastern Atlantic Ocean and the Mediterranean Sea.
Enoploteuthis is a genus of squid in the family Enoploteuthidae. The species of Enoploteuthisare most easily recognised by having a larger tail when compared to the other genera in the Enoploteuthidae. The tail's size is emphasised not having the fins extending along its sides. In related genera there is a narrow extension of the fins along the tail. Other characteristics include the presence of suckers on the distal portion of arms IV where there at no photophores present; the tentacular club has two rows of hooks and no marginal suckers; on the buccal crown there are typical chromatophores on the aboral surface but on the oral surface there may be some light skin pigmentation. They have 9-10 photophores on the eye and they have complex photophores in the skin. In the females the Spermatangia receptacles are at the posterior junction of muscles used to retract the funnel and the muscles which retract the head. Enoploteuthis differs from other genera of the Enoploteuthidae in having two rather than three types of photophores in its integument and these are on the ventral areas of the head, funnel and mantle. All species of Enoploteuthis which have been studied have the most complex type of photophoreand seems to be a distinctive characteristic of this genus. Enoploteuthis contains the largest species in the family, attaining a mantle length of 130mm.
Sepia zanzibarica, or the Zanzibar cuttlefish, is a species of cuttlefish native to the Indian Ocean.
Heteroteuthis dispar, also known as the odd bobtail, is a small deep water squid found in the North Atlantic Ocean and the Mediterranean Sea.
Sepia elegans, the elegant cuttlefish, is a species of cuttlefish in the family Sepiidae from the eastern Atlantic Ocean and the Mediterranean Sea. It is an important species for fisheries in some parts of the Mediterranean where its population may have suffered from overfishing.
Euprymna morsei, the Mimika bobtail squid, is a species of Indo-Pacific bobtail squid from the family Sepiolidae.
Sepia bertheloti, the African cuttlefish, is a species of cuttlefish from the family Sepiidae which is found in the warmer waters of the eastern Atlantic Ocean off Africa.
Sepia orbignyana, the pink cuttlefish, is a species of small cuttlefish from the family Sepiidae. It is occurs in the temperate and tropical waters of the eastern Atlantic Ocean.
Afrololigo mercatoris, commonly known as the Guinean thumbstall squid, is a small species of squid in the family Loliginidae from the eastern central Atlantic Ocean. It is the only species in the monotypic genus Afrololigo.
Alloteuthis media, the midsize squid or little squid is a species of squid in the family Loliginidae from the eastern Atlantic and the Mediterranean Sea. It is generally a by catch species in trawl fisheries, although there is an active fishery in the western Mediterranean.
Doryteuthis is a genus of squid from the waters of the western Atlantic and eastern Pacific off the coast of the Americas species are the common inshore squids of American waters. Some species are important quarry species for fisheries.
Lolliguncula is a genus of squid from the family Loliginidae from the eastern Pacific and western Atlantic, known as brief squid. The genus is divided into two subgenera Lolliguncula and Loliolopsis. They are rather small squids with a maximum mantle length of 120mm, that inhabit shallow warm seas, although some species have been recorded in areas of low salinity. They are typified by having a short mantle, which is round at the posterior; and fins that are broader than long, but which have no posterior lobes. The males produce spermatophores with a long cement body and they lack a ventral crest on their hectocotylus. Their suckers have square teeth which ring the entire margin or are placed distally. The males do not have enlarged suckers on the left ventral arm. The tentacular club is expanded and contains suckers in four series. The two subgenera differ in the morphology of the hectocotylus.
Slosarczykovia is a monotypic genus of squid, its sole representative being Slosarczykovia circumantarctica. Slosarczykovia is placed in the family Brachioteuthidae.
Enoploteuthis leptura, the hooked enope squid, is a species of squid from the family Enoploteuthidae. It is the type species of the genus Enoploteuthis, which is in turn the type genus of the Enoploteuthidae.
Ornithoteuthis volatilis, the shiny bird squid, is a squid from the subfamily Ommastrephinae, the flying squids, of the family Ommastrephidae part of the pelagic squid order Oegopsida. It is a tropical and sub-tropical species which is widely distributed in the Indo-Pacific oceans. It is slightly larger than the closely related species Ornithoteuthis antillarum of the Atlantic Ocean.
The Antarctic flying squid is a species of squid from the subfamily Todarodinae of the family Ommastrephidae, a family of pelagic squid from the order Oegopsida. It has a circumglobal distribution in the seas around the lower latitudes of the Southern Oceans.
Uroteuthis noctiluca, commonly known as the luminous bay squid, is a species of squid native to shallow water on the eastern coast of Australia. It uses a pair of luminous organs to camouflage itself from predators at night.
