Vampyromorpha

	Vampyromorpha Vampyromorphida is an order of cephalopods comprising one known extant species (''Vampyroteuthis infernalis'') and many extinct taxa. Physically, they somewhat resemble octopuses (their closest relatives), but the eight arms are united by a web of skin, and two smaller cilia are also present. Properly speaking, the vampire squid does not possess cilia, but cirri (cilia-like projections).

picture info	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]
picture info	Vampyronassa ''Vampyronassa rhodanica'' ("vampire fish trap") is an extinct vampyromorph cephalopod known from around 20 fossils from the Lower Callovian (165–164 Ma) of La Voulte-sur-Rhône, Ardèche, France. Morphology ''Vampyronassa'' reached total length about . This taxon differs from the modern vampire squid in having longer first dorsal arms, a larger hyponome, and a more elongated mantle. Original description described possible luminous organs, however in restudy they could not be confirmed. It had eight arms with uniserial suckers flanked by cirri, same as modern vampire squid. Retractile filaments that is known from modern vampire squid is not known in ''Vampyronassa''. Like vampire squid, ''Vampyronassa'' lacked of ink sac. Classification ''Vampyronassa'' shares some characters with modern vampire squid ''Vampyroteuthis'', such as lack of ink sac and unique type of sucker attachment. Analysis supports the sister relationship between ''Vampyronassa'' and ''Vampyroteuth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Teudopsis ''Teudopsis'' is a genus of the coleoid cephalopod family Teudopsidae, known only from Lower Jurassic gladii. It has been reported from Alberta, Canada and Europe. The life appearance of Teudopsis is probably best inferred by its close relative Trachyteuthis ''Trachyteuthis'' is a genus of fossil cephalopod, comprising five species: ''T. hastiformis'', ''T. latipinnis'', ''T. nusplingensis'', ''T. teudopsiformis'', ''T. covacevichi'' and ''T. chilensis''. Taxonomy The taxonomic placement of ''Tr .... A fossil with soft tissue preservation shows that this animal may have had two mantle fins, which may also be the case for Teudopsis.
