Austrorossia australis, often called the big bottom bobtail squid, is a species of bobtail squid in the family Sepiolidae. [1] This species lives in sandy and muddy environments [2] from 131 to 665 meters deep, in waters away from South Australia, New South Wales, Victoria, Tasmania, and Queensland. [3]
Its coloring is pinkish to a purple brown coloring, the dorsal mantle is not fused with the head, and it has fins that are wide and short. [2] It has a length of 3.4 cm for males, and 6.3 for females. [4] Female A. australis lay their eggs in small clusters and then leave them unattended, and they may spawn several times in a year. [2]
Its only threat is its being harvested, and it has minor fishery interests. It has no need for any conservation measures, and has been placed as "Least Concern" by the IUCN Red List. [3]
Peale's dolphin is a small dolphin found in the waters around Tierra del Fuego at the foot of South America. It is also commonly known as the black-chinned dolphin or even Peale's black-chinned dolphin. However, since Rice's work Peale's dolphin has been adopted as the standard common name.
Euprymna tasmanica, also known as the southern dumpling squid or southern bobtail squid, is a bobtail squid that lives in the shallow temperate coastal waters of southern Australia's continental shelf. It lives for between 5 and 8 months and the adults can grow up to 6 or 7 cm long with a mantle length of 3 to 4 cm. They are found in seagrass beds or areas with soft silty or muddy bottoms from Brisbane on the east coast to Shark Bay on the west, as well as around Tasmania. Southern dumpling squid are nocturnal and during the day hide in sand or mud covered in a mucus-lined coat of sediment. If disturbed acid glans can quickly remove this coat as an additional decoy to ink squirting.
The gummy shark, also known as the Australian smooth hound, flake, sweet william or smooth dog-shark, is a species of ground shark in the genus Mustelus of the family Triakidae. These small to medium-sized bottom-dwelling sharks are found mostly in, but are not limited to, the area around the southern seas of Australia and is commonly baited and fished for cuisine because of its taste and market prices. According to a 2021 paper by White, Arunrugstichai & Naylorn (2021), Mustelus walkeri is the same animal as M. antarcticus. One theory is that M. walkeri is a subpopulation of M. antarcticus.
The Australian weasel shark is an uncommon species of ground shark in the family Hemigaleidae. It inhabits shallow waters off northern Australia to a depth of 170 m (560 ft); smaller sharks frequent sand and seagrass habitat and shift to coral reefs as they grow older. A slim, drab species reaching a length of 1.1 m (3.6 ft), it has sickle-shaped fins with dark tips on the second dorsal fin and caudal fin upper lobe. Its upper teeth are broad with strong serrations only on the trailing edge. The lateral line along each side is prominent and exhibits a downward curve below the second dorsal fin.
Austrorossia mastigophora is a species of bobtail squid native to western, southern and eastern Africa, from Guinea and Somalia to the Cape of Good Hope. A doubtful record of this species exists from Chile. It lives at depths to approximately 640 m.
Rossiinae is a subfamily of bobtail squid encompassing four genera and around twenty species, two of which require further verification.
Rossia palpebrosa, also known as the warty bobtail squid, is a species of bobtail squid native to the northern Atlantic Ocean.
Austrorossia enigmatica is a species of bobtail squid native to the southeastern Atlantic Ocean; it occurs off the coast of southern Africa from Namibia to Cape Province. It lives at depths from 276 to 400 m.
Idiosepius pygmaeus, also known as the two-toned pygmy squid or tropical pygmy squid, is a species of bobtail squid native to the Indo-Pacific. It occurs in waters of the South China Sea, Japan, Philippines, Palau, Indonesia, Northern Mariana Islands, as well as northern and northeastern Australia. It inhabits shallow, inshore waters.
Sepiola atlantica, also known as the Atlantic bobtail, is a species of bobtail squid native to the northeastern Atlantic Ocean and the Mediterranean Sea.
Sepiolina nipponensis, also known as the Japanese bobtail squid, is a bobtail squid and one of two species in the genus Sepiolina. It is found in the Western Pacific in apparently widely separated populations, the most southerly of which is in the Great Australian Bight in South Australia and Western Australia, and there are populations from the Philippines northwards to Taiwan, Fujian and southern Honshū.
Heteroteuthis dispar, also known as the odd bobtail, is a small deep water squid found in the North Atlantic Ocean and the Mediterranean Sea.
Euprymna berryi, commonly called hummingbird bobtail squid or Berry's bobtail squid among various other vernacular names, is a species of mollusc cephalopod in the family Sepiolidae.
Rossia pacifica, also known as the stubby squid, is a species of bobtail squid native to the northern Pacific Ocean. It usually occurs in winter on sandy slopes away from strong currents in moderately shallow water. In summer it moves to deeper water where it breeds. The female cements the egg capsules under a stone or in some other concealed location, and both male and female die soon after breeding.
The Pacific spiny dogfish is a common species of the Squalidae (dogfish) family of sharks and are among the most abundant species of sharks in the world. This species is closely related to Squalus acanthias and for many years they were treated as a single species. Recent research, using meristic, morphological and molecular data led to the resurrection of the Pacific spiny dogfish as a separate species. The American Fisheries Society recommends the common name "Pacific spiny dogfish" for Squalus suckleyi over alternatives such as "spotted spiny dogfish" and "North Pacific spiny dogfish" and "spiny dogfish" for Squalus acanthias.
Sepioteuthis australis, commonly known as the southern calamari or the southern reef squid, is a species of reef squid that is native to oceans off the coast of Australia and New Zealand. This species is caught commercially by trawling, as bycatch in the prawn fishing industry and by recreational anglers.
Neorossia caroli, the Carol bobtail squid, is a species of bobtail squid belonging to the family Sepiolidae.
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. 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).
Austrorossia bipapillata, or the big-eyed bobtail squid, is a species of cuttlefish.
