Taonius Borealis
''Taonius borealis'' is a glass squid belonging to the genus Taonius. It is found in the North Pacific Ocean. ''Taonius borealis'' is a transparent to dark purple color. They have tentacles or arms, and each arm consists of two suckers per row. The tentacular club armature consists of four hooked suckers per row, medial suckers with one or two large hooks and several small cusps. The maximum size is mantle length. Their regular habitat is mesopelagic to bathypelagic. They mostly feed on shrimps, small fishes, including myctophids, and other squids. Predators include whales, sharks, and squids.

Glass Squid
The family Cranchiidae comprises the approximately 60 species of glass squid, also known as cockatoo squid, cranchiid, cranch squid, or bathyscaphoid squid. Cranchiid squid occur in surface and midwater depths of open oceans around the world. They range in mantle length from to over , in the case of the colossal squid. The common name, glass squid, derives from the transparent nature of most species. Cranchiid squid spend much of their lives in partially sunlit shallow waters, where their transparency provides camouflage. They are characterised by a swollen body and short arms, which bear two rows of suckers or hooks. The third arm pair is often enlarged. Many species are bioluminescent organisms and possess light organs on the undersides of their eyes, used to cancel their shadows. Eye morphology varies widely, ranging from large and circular to telescopic and stalked. A large, fluid-filled chamber containing ammonia solution is used to aid buoyancy. This buoyancy syste ...

Taonius
''Taonius'' is a small genus of glass squid. Although it comprises only three recognised species, it has been suggested there may be as many as five species. ''Taonius borealis'' is found in the North Pacific Ocean and ''Taonius pavo'' is found in the Atlantic and possibly SW Indian Ocean. Some teuthologists dispute Voss's synonymy of ''Belonella'' with ''Taonius''. The genus contains bioluminescent species. Species Three species are currently placed in ''Taonius'': *''Taonius borealis'' (Nesis, 1972) *''Taonius belone'' (Carl Chun, Chun, 1906) *''Taonius pavo'' (Lesueur, 1821) References External links Tree of Life web project: ''Taonius'' Squid Cephalopod genera Bioluminescent molluscs {{squid-stub ...

Pacific Ocean
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 continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Cephalopod Limb
All cephalopods possess flexible limbs extending from their heads and surrounding their cephalopod beak, beaks. These appendages, which function as muscular hydrostats, have been variously termed arms, legs or tentacles. Description In the scientific literature, a cephalopod ''arm'' is often treated as distinct from a ''Tentacle#Tentacles in invertebrates, tentacle'', though the terms are sometimes used interchangeably, often with the latter acting as an umbrella term for cephalopod limbs. Generally, arms have suckers along most of their length, as opposed to tentacles, which have suckers only near their ends.Young, R.E., M. Vecchione & K.M. Mangold 1999Cephalopoda Glossary Tree of Life web project. Barring a few exceptions, octopuses have eight arms and no tentacles, while squid and cuttlefish have eight arms (or two "legs" and six "arms") and two tentacles.Norman, M. 2000.

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 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 jet propulsion, and largely locate their prey by sight. They are among the most intelligent o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
