Sepiadariidae Family of cuttlefishes

Sepiadariidae is a family of cuttlefish, cephalopods in the order Sepiida.

<i>Idiosepius</i>

Idiosepius is a genus of mollusk in the family Idiosepiidae. Members of this genus represent no interest to commercial fisheries.

Whip-lash squid Family of cephalopods known as whip-lash squid

The Mastigoteuthidae, also known as whip-lash squid, are a family of small deep-sea squid. Approximately 20 known species in six genera are represented, with members found in both the mesopelagic and bathypelagic zone of most oceans. Originally described by Verill in 1881, it was later lowered by Chun (1920) to a subfamily (Mastigoteuthinae) of the Chiroteuthidae. However, Roper et al. (1969) raised it back to the family level, and this has not been changed since. The taxonomy of this family is extremely unstable, and there have been at times one genus, two genera and four subgenera(Salcedo-Vargas & Okutani, 1994), two genera and several 'groups', five genera and one species with an uncertain placement, or six genera.

Taoniinae

Taoniinae is a subfamily containing ten genera of glass squids.

Mastigoteuthis is a genus of whip-lash squid containing at least seven valid species. Some teuthologists consider Idioteuthis synonymous with this taxon.

Idiosepiidae is a family of mollusk in the class Cephalopoda. This family appears to be related to the cuttlefish in the order Sepiida and the bobtail squid in the order Sepiolida but the exact placement of this family within the Decapodiformes is incertae sedis.

Sepiolinae

Sepiolinae is a subfamily of bobtail squid encompassing 5 genera and more than 30 species.

<i>Semirossia</i>

Semirossia is a genus of bobtail squid comprising three species.

<i>Euprymna</i>

Euprymna is a genus of bobtail squid comprising a number of species.

<i>Sepioloidea</i> Genus of cuttlefishes

Sepioloidea is a genus of cuttlefish comprising three species.

Idiosepius minimus is a species of bobtail squid native to the "coast of Africa" where it occurs in shallow, inshore waters. Specimens collected under the junior synonyms I. biserialis and I. macrocheir were described from Mozambique. Since the further collecting effort off Mozambique has seen additional specimens gained. As a result it has been inferred that this species has a relatively restricted distribution since Idiosepius has not been recorded elsewhere in Africa.

<i>Sepiadarium kochi</i> Species of cuttlefish

Sepiadarium kochi, common name tropical bottletail squid or Koch's bottletail squid, is a species of cuttlefish.

<i>Teuthowenia megalops</i>

Teuthowenia megalops, sometimes known as the Atlantic cranch squid, is a species of glass squid from the subarctic and temperate waters of the northern Atlantic Ocean. They are moderately sized squid with a maximum mantle length of 40 cm (16 in). Their very large eyes are the source for the specific name megalops. Like other members of the genus Teuthowenia, they are easily recognizable by the presence of three bioluminescent organs (photophores) on their eyeballs.

Sepioloidea magna is a species of cuttlefish, more precisely a bottletail squid, of the family Sepiadariidae, indigenous to the waters off northern Australia. It was described by Amanda Reid in 2009 from specimens which were found in the Museum and Art Gallery of the Northern Territory in Darwin, Northern Territory. It differs from its congeners in the genus Sepioloidea in its larger size, its modified hectocotylus, the number of tentacular club suckers and the absence of an obvious colour pattern It has been recorded from relatively deep water, between 225m and 300m, in the Arafura Sea north of Darwin, Australia, and south of the eastern Indonesian islands of Tanimbar. Other specimens identified as Sepioloidea and occurring at similar depths, from the North West Shelf, Scott Reef and the Timor Sea probably also represent this species.

Loliolus is a genus of squid from the family Loliginidae from the Indo-Pacific region. The genus is divided into two subgenera Loliolus and Nipponololigo. They are small squids of less than 150mm in mantle length which have an expanded tentacular club. This club has 4 series of suckers. The sucker rings have plate-like teeth which are square in shape all around them. The males' hectocotylus has a ventral crest which is created by the fusion of the protective membrane with the ventral series of papillae and this crest completely obscures the conical shape of the papillae. The mantle is rounded posteriorly and lacks the posterior tail-like lobe while the fins are positioned on the rear of the mantle and extend to the posterior tip of the mantle. Their eggs are small and the males' spermatophore has a short cement body. They do not possess photophores. The two subgenera are distinguished by the hectocotylus which in Loliolus encompasses the entire arm and there are no unmodified suckers while in Nipponololigo the arm is only partly hectocotylsed and has normal suckers at its base.

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.

Lycoteuthinae

Lycoteuthinae is a subfamily of squid from the family Lycoteuthidae. They are found in tropical and subtropical waters. They are characterised by the possession of oval photophores on the tentacles, eyeballs and viscera in all species and on the arms, head, mantle and fins in some. Some species also show strong sexual dimorphism. The subfamily contains all of the species classified under Lycoteuthidae, except for Lampadioteuthis megaleia which differs from the Lycoteuthins by the bearing of a hectocotylised arm in males.

<i>Todarodes</i>

Todarodes is a genus of flying squid from the subfamily Todarodinae, of which it is the type genus. The genus contains five species which are partially allopatric but between them their distributions encompass most of the world's oceans and seas. These squid have a funnel groove with foveola, a hectocotylised fourth arm and tentacular stalks which lack free trabeculae.

<i>Sepioloidea lineolata</i> Species of cuttlefish

Sepioloidea lineolata or more commonly known as the striped pyjama squid or the striped dumpling squid is a type of cuttlefish that inhabits the Indo-Pacific Oceans of Australia. The striped pyjama squid lives on the seafloor and is both venomous and poisonous. When fully mature, a striped pyjama squid will only be about 7 to 8 centimeters in length.
