Pyroteuthidae
Pyroteuthidae (the fire squids) is a family of squids. The family comprises two genera. Species are diurnally mesopelagic, migrating into surface waters during the night. The family is characterised by the tentacles, which have a permanent constriction and bend near the base; and photophores occurring on the tentacles, eyeballs, and viscera In biology, an organ is a collection of tissues joined in a structural unit to serve a common function. In the hierarchy of life, an organ lies between tissue and an organ system. Tissues are formed from same type cells to act together in a f .... Members reach mantle lengths of 23–50 mm. Paralarvae of the family are common around the Hawaiian Islands, with up to 17% of collected specimens in the area belonging to Pyroteuthidae.John R. Bower, Michael P. Seki, Richard E.

Firefly Squid
The firefly squid (''Watasenia scintillans''), also commonly known as the sparkling enope squid or hotaru-ika in Japan, is a species of squid in the family Enoploteuthidae. It is the sole species in the monotypic genus ''Watasenia''. These tiny squid are found on the shores of Japan in springtime during spawning season, but spend most of their lives in deeper waters between . They are bioluminescent organisms and emit blue light from photophores, which some scientists have hypothesized could be used for communication, camouflage, or attracting food, but it is still unclear in the scientific community exactly how this species uses their bioluminescence. The firefly squid is a predator and actively hunts its food, which includes copepods, small fish, and other squids. The lifespan of a firefly squid is about one year. At the end of their lives females return close to shore to release their eggs, and then die shortly thereafter. This mass migration of firefly squid to the shore is a ...

Enoploteuthis
''Enoploteuthis'' is a genus of squid in the family Enoploteuthidae. The species of ''Enoploteuthis''are 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.

Pyroteuthis
''Pyroteuthis'' is a genus of squid in the family Pyroteuthidae. It is differentiated from the genus '' Pterygioteuthis'' by size, head shape and behaviour. Species within the genus are separated by the arrangement of tentacular photophores; the shape of the hectocotylus, and the shape of the hectocotylus hooks. With the exception of the Tropical Eastern Pacific, the genus is circumpolar in tropical and temperate oceans. The species '' P. addolux'' is the only member to occur in the North Pacific The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continen ....

Nematolampas
''Nematolampas'' is a genus of squid from the family Lycoteuthidae. The genus comprises two species both of which are known from only a few males. The type species, ''Nematolampas regalis'' has been recorded from the subtropical South Pacific and the second species, '' Nematolampas venezuelensis'', is from the tropical western North Atlantic. The main distinguishing feature of this genus is that arms III are very elongated and thread-like and have no suckers near their tips. As only males have been captured it is not known if this feature is present in females. Species There are currently two species classified under this genus: *''Nematolampas regalis ''Nematolampas regalis'', the regal firefly squid is a small, little-known species of squid from the family Lycoteuthidae which is found in the subtropical South Pacific Ocean.

Lycoteuthis
''Lycoteuthis'' is a genus containing two species of squid: '' Lycoteuthis springeri'' and ''Lycoteuthis lorigera''. They are small animals which grow up to 8 cm in length. These squid live in the deep sea at depths of up to 3000 metres, making horizontal migrations within their range along the steep shelves. ''Lycoteuthis'' are particularly characterised by their photophores, shining organs which give them their German name "Miracle Lamps". The photophores are located in various parts of the body, with males having them on their mantle and head. The light of these photophores results from bioluminescence. The photophores serve as camouflage Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the ..., since the body appears almost transparent by the light effects and normally visible ...

Lampadioteuthis
''Lampadioteuthis megaleia'' is a small, colorful squid from the family Lycoteuthidae, it is the only species in the only genus in the monotypic subfamily Lampadioteuthinae, it is sometimes known as the wonderful firefly squid. It differs from the other species of the Lycoteuthidae mainly by having a hectocotylus in the males and by the possession of a rostrum on the gladius. Description ''Lampadioteuthis megaleia'' is a small squid which grows to a mantle length of 40 mm. In males the right ventral arm is hectocotylized with an enlarged protective membrane over the mid-arm. It has four ocular photophores, arranged as three in a ventral line and one positioned laterally. The tentacles have five photophores which are set on a stalk. There are circular anal photophores on either side of the rectum, single elongated branchial photophores lie at the base of each gill, there are no abdominal photophores and a single photophore is situated to the rear of the abdomen between the i ...

Abralia
''Abralia'' is a genus of squid comprising around 20 species from the Family (biology), family Enoploteuthidae. They are small squid which can be found in the epipelagic to mesopelagic zones while some species are found in water with shallow substrates on steep slopes on the boundary of the mesopelagic zone. They are distinguished from other members of the Enoploteuthidae by not normally having large, black photophores at the tips of arms IV, although if these are present they are not covered in black chromatophores, and having fins which extend beyond their tail. The photophores of the integument are characteristicand are found in the three types . "Lensed" photophores are a blue color with a white ring, "simple" photophores are small and violet-colored and the "complex" photophores are surrounded by small green satellite points and have a green centre. The complex photophores will frequently appear to be blue depending on their physiological state. The integument also has small ...
