Sepiadariidae is a family of coleoid cephalopods in the order Sepiida.
Idiosepius is a genus of squids in the family Idiosepiidae. They are small, reaching mantle lengths of no more than about 21 mm (0.8 in); members of this genus represent no interest to commercial fisheries. They occur in tropical and temperate waters throughout the Indo-Pacific, primarily in association with seagrass and mangrove roots.
Coleoidea or Dibranchiata, is one of the two subclasses of cephalopods, containing all the various taxa popularly thought of as "soft-bodied" or "shell-less". Unlike its extant sister group Nautiloidea, whose members have a rigid outer shell for protection, the coleoids have at most an internal shell called cuttlebone or gladius that is used for buoyancy or as muscle anchorage. Some species, notably incirrate octopuses, have lost their cuttlebone altogether, while in some it has been replaced by a chitinous support structure. A unique trait of the group is the ability to edit their own RNA.
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.
Decapodiformes is a superorder of Cephalopoda comprising all cephalopod species with ten limbs, specifically eight short arms and two long tentacles. It is hypothesized that the ancestral coleoid had five identical pairs of limbs, and that one branch of descendants evolved a modified arm pair IV to become the Decapodiformes, while another branch of descendants evolved and then eventually lost its arm pair II, becoming the Octopodiformes.
Inioteuthis is a genus of bobtail squid comprising three species.
Sepiadarium auritum is a species of cuttlefish native to the eastern Indian Ocean off northwestern Australia.
Sepiadarium gracilis is a species of cuttlefish native to the Indo-Pacific; it occurs in the South China Sea and off the western Philippines.
Sepiadarium is a genus of cuttlefish comprising five species.
Sepioloidea is a genus of cephalopod 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 then, 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.
Sepioloidea pacifica, also known as the Pacific bobtail squid, is a species of cuttlefish native to the southern Pacific Ocean; it occurs off New Zealand in the west and in the Nazca and Sala y Gomez submarine ridges in the east.
Neocoleoidea is a large group of marine cephalopods. This cohort contains two extant groups: Decapodiformes and Octopodiformes. Species within this group exist in all major habitats in the ocean, in both the southern and northern polar regions, and from intertidal zones to great depths. Whilst conventionally held to be monophyletic, the only morphological character for the group is the presence of suckers: although the presence of these features in the belemnites suggests that they do not support the Neocoleoidea, and hence that the group may be paraphyletic.
Sepiadarium kochi, common name tropical bottletail squid or Koch's bottletail squid, is a species of cuttlefish.
Amanda "Mandy" Louise Reid is an Australian taxonomist and malacologist. She held the position of collection manager of malacology at the Australian Museum from 2010 to 2023. She is a published researcher and author. Her research has resulted in the description of many species of velvet worms and cephalopods.
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.
Sepioloidea lineolata or more commonly known as the striped pyjama squid or the striped dumpling squid is a type of bottletail squid that inhabits the Indo-Pacific Oceans of Australia. Although traditionally falling within Sepiida, the cuttlefish order, it lacks a cuttlebone. More recent phylogenomic evidence suggests bottletail and bobtail squid may form their own order, Sepiolida. 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 centimetres in length. Baby striped pyjama squid can be smaller than 10 millimetres (0.39 in).
Sepiadarium austrinum, the southern bottletail squid, is a species of cuttlefish in the genus Sepiadarium. It was first described by S. Stillman Berry in 1921 based on a specimen found in St. Vincent Bay in South Australia.
