Octopus2
An octopus ( : octopuses or octopodes, see below for variants) is a soft-bodied, eight- limbed mollusc of the order Octopoda (, ). The order consists of some 300 species and is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids. Like other cephalopods, an octopus is bilaterally symmetric with two eyes and a beaked mouth at the center point of the eight limbs. The soft body can radically alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight appendages behind them as they swim. The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse of all invertebrates. Octopuses inhabit various regions of the ocean, including coral reefs, pelagic waters, and the seabed; some live in the intertidal zone and others at abyssal depths. Most species grow quickly, mature early, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incirrina
Incirrata (or Incirrina) is a suborder of the order Octopoda. The suborder contains the classic " benthic octopuses," as well as many pelagic octopus families, including the paper nautiluses. The incirrate octopuses are distinguished from the cirrate octopuses by the absence in the former of the "cirri" filaments (found with the suckers) for which the cirrates are named, as well as by the lack of paired swimming fins on the head, and lack of a small internal shell (the "shell" of '' Argonauta'' species is not a true shell, but a thin calcite egg case).

Megaleledonidae
Megaleledonidae is a family of octopuses in the superfamily Octopodoidea. It was formerly placed in the family Octopodidae ''sensu lato'' as the subfamily Megaleledoninae but more recent studies have raised this taxon as a valid family. Reproduction Megaleledonidae are known to produce both fewer and larger offspring than octopods that live in more tropical climates. The eggs produced by Megaleldonidae are typically large with very slow embryonic development that can take up the majority of their lifecycle including from months to years. Genera The following genera are included within the family Megaleledonidae: * '' Adelieledone'' Allcock, Hochberg, Rodhouse & Thorpe, 2003 * '' Bathypurpurata'' Vecchione, Allcock & Piatkowski, 2005 * '' Bentheledone'' Robson, 1932 * '' Graneledone'' Joubin, 1918 * '' Megaleledone'' Iw.

Amphitretidae
Amphitretidae is a family of mesopelagic octopods which contains three subfamilies, formerly classified as families in their own right. It is classified in the superfamily Octopodoidea. Species in the family Amphipetridae are characterised by having a single row of suckers on each arm (uniserial suckers), a gelatinous body and non hemispherical eyes. Taxonomy There are three subfamilies within Amphipetridae: * Subfamily Amphitretinae Hoyle, 1886 ** Genus '' Amphitretus'' Hoyle, 1885 * Subfamily Bolitaeninae Chun, 1911 ** Genus '' Bolitaena'' Steenstrup, 1859 ** Genus '' Japetella'' Hoyle, 1885 ** Genus '' Dorsopsis'' Thore, 1949 (''taxon inquirendum In biological classification, a ''species inquirenda'' is a species of doubtful identity requiring further investigation.

Eledonidae
''Eledone'' is a genus of octopuses forming the only genus in the family Eledonidae. It is mainly distributed in the northern and southern Atlantic Ocean, with one species, '' E. palari'', described from the southwestern Pacific Ocean and eastern Indian Ocean in waters around Indonesia and Australia and another, ''E. microsicya'', from the western Indian Ocean. One species, ''E. thysanophora'', is now regarded as a synonym of the brush-tipped octopus (''Eledone schultzei''). Species The following species are currently classified as being in the genus ''Eledone'': * '' Eledone caparti'' Adam, 1950 * '' Eledone cirrhosa'' (Lamarck, 1798) – curled octopus * '' Eledone gaucha'' Haimovici, 1988 * '' Eledone massyae'' Voss, 1964 – combed octopus * ''Eledone microsicya'' * (Rochebrune, 1884) * ''Eledone moschata ''Eledone moschata'', the musky octopus, is a species of octopus belonging to the family Octopodidae.

Argonautidae
The Argonautidae are a family of pelagic cephalopods that inhabit tropical and temperate oceans of the world. The family encompasses the modern paper nautiluses of the genus '' Argonauta'' along with several extinct genera of shelled octopods. Though argonauts are derived from benthic octopuses, they have evolved to depart the sea floor and live their life-cycle in the open seas. The family is characterised by brittle white shells constructed by the females, but which the dwarf male argonauts lack. These shells are primarily egg-cases, and are not attached to the body of the female. Paper nautiluses are often found washed up on beaches and are valued for their delicate beauty. The shell also plays the role of a buoyancy device, which the female controls by varying the amount of gulped air.Finn, Julian K., and Mark D. Norman.

Vampire Squid
The vampire squid (''Vampyroteuthis infernalis'', lit. 'vampire squid from hell') is a small cephalopod found throughout temperate and tropical oceans in extreme deep sea conditions. The vampire squid uses its bioluminescent organs and its unique oxygen metabolism to thrive in the parts of the ocean with the lowest concentrations of oxygen. It has two long retractile filaments, located between the first two pairs of arms on its dorsal side, which distinguish it from both octopuses and squids, and places it in its own order, Vampyromorphida, although its closest relatives are octopods. As a phylogenetic relict, it is the only known surviving member of its order. The first specimens were collected on the Valdivia Expedition and were originally described as an octopus in 1903 by German teuthologist Carl Chun, but later assigned to a new order together with several extinct taxa. Discovery The vampire squid was discovered during the Valdivia Expedition (1898–1899), led by Carl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
