Octopoteuthidae
The Octopoteuthidae are a family of squid comprising two genera. The family is characterized by tentacles which cease to grow after the paralarval stage, and the use of a penis, instead of a hectocotylus A hectocotylus (plural: ''hectocotyli'') is one of the arms of male cephalopods that is specialized to store and transfer spermatophores to the female. Structurally, hectocotyli are muscular hydrostats. Depending on the species, the male may use i ....

Taningia
''Taningia'' is a genus of squid in the family Octopoteuthidae. For over 150 years, it has been believed to comprise a single species known as ''Taningia danae.'' Recently it has been shown to contain at least two new species ('' T. fimbria'', ''T. rubea''). Another species, '' Taningia persica'', has historically been referred to but has been questioned. This genus is named after Danish fisheries biologist Åge Vedel Tåning Åge Vedel Tåning (27 July 1890 – 26 September 1958 in Copenhagen) was a Danish ichthyologist. He was a director of the Carlsberg Laboratory, the Dana collection and the Danish Fisheries Research Station. Lanternfish genus ''Taaningichthys'' wa ... (1890-1958).

Octopoteuthis Danae
''Octopoteuthis danae'' is a little known species of small squid in the genus '' Octopoteuthis'' of the family Octopoteuthidae. They belong to the pelagic squid order Oegopsida. It is found in the Atlantic Ocean. It is distinguished from the other known similar Atlantic species, '' Octopoteuthis megaptera'', by having a shorter tail which has two photophores. Its specific name honours James Dwight Dana (1813–1895) the American mineralogist and geologist A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them.

Octopoteuthis Sicula
''Octopoteuthis'' is a genus of squid. It is one of two genera in the family Octopoteuthidae, the other being ''Taningia''. Both ''Octopoteuthis'' and ''Taningia'' are characterized by their lack of tentacles for the majority of their life cycle, and have traits characteristic of both squids and octopods. The species limits of the genus are in need of further research, for example some authorities have stated that the Mediterranean species '' Octopoteuthis sicula'' is apparently the senior synonym of ''Octopoteuthis danae'' and that it is very closely related to, or possibly conspecific with, '' Octopoteuthis megaptera''.

Octopoteuthis Deletron
''Octopoteuthis deletron'' is a species of squid in the genus '' Octopoteuthis'' of the family Octopoteuthidae. They belong to the pelagic squids of order Oegopsida. Found at depths of in the Pacific Ocean, they have been known to grow to . ''O. deletron'' has been found to break off its arms as a defense strategy. The squid digs hooks in one of its arms into a predator and jets away, leaving the arm in the predator's skin. The male ''O. deletron'' has a penis, which is unusual among squids. Males find it difficult to detect the sex of other individuals they encounter in the dark depths, so they have adopted a strategy of attaching sperm packets to all individuals they meet. ''O. deletron'' are the most common species found in the stomachs of northern elephant seals sampled off the coast of California. It is an important prey item of the giant grenadier. It is also eaten by the enigmatic Perrin's beaked whale Perrin's beaked whale (''Mesoplodon perrini'') is part of the too ...

Squid
True squid are molluscs with an elongated soft body, large eyes, eight arms, and two tentacles in the superorder Decapodiformes, though many other molluscs within the broader Neocoleoidea are also called squid despite not strictly fitting these criteria. Like all other cephalopods, squid have a distinct head, bilateral symmetry, and a mantle. They are mainly soft-bodied, like octopuses, but have a small internal skeleton in the form of a rod-like gladius (cephalopod), gladius or pen, made of chitin. Squid diverged from other cephalopods during the Jurassic and occupy a similar role to teleost fish as open water predators of similar size and behaviour. They play an important role in the open water food web. The two long tentacles are used to grab prey and the eight arms to hold and control it. The beak then cuts the food into suitable size chunks for swallowing. Squid are rapid swimmers, moving by Aquatic locomotion#Jet propulsion, jet propulsion, and largely locate their ...
