Oegopsina
Oegopsida is one of the four orders of squid in the superorder Decapodiformes, in the class Cephalopoda. Together with the Myopsina, it was formerly considered to be a suborder of the order Teuthida, in which case it was known as Oegopsina. This reclassification is due to Oegopsina and Myopsina not being demonstrated to form a clade. The Oegopsida are an often pelagic squid, with some nerito-oceanic species associated with sea mounts. They consist of 24 families and 69 genera. They have these characters in common: the head is without tentacle pockets, eyes lack a corneal covering, arms and tentacle clubs may have hooks, the buccal supports are without suckers, and oviducts in females are paired. Two families, the Bathyteuthidae and Chtenopterygidae, which have features characteristic of the Myopsida while retaining others common to the Oegopsina, were formerly placed in the family, but are now placed in their own order Bathyteuthida. The Oegopsida differ from the coastal Myops ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ommastrephidae
Ommastrephidae is a family (biology), family of squid containing three subfamilies, 11 genus, genera, and over 20 species. They are widely distributed globally and are extensively fished for food. One species, ''Todarodes pacificus'', comprised around half of the world's cephalopod catch annually. Some members of Ommastrephidae are known for their Aquatic locomotion#Jet propulsion, jet-propelled flight, earning them the common name of "flying squid". Description The ommastrephids are small to large squids, with Mantle (mollusk), mantle lengths ranging from that of the glass squid (''Hyaloteuthis pelagica'') at ,Nesis, K. N. 1982.

Myopsida
Myopsida is one of the four orders of squid. It consists of two families: the monotypic '' Australiteuthis'' and the diverse and commercially important Loliginidae (~50 species). Some taxonomists classify this taxon as a suborder of the order Teuthida, in which case it is known as Myopsina. This reclassification is due to Myopsina and Oegopsina not being demonstrated to form a clade. A number of morphological features distinguish members of Myopsida from those of its sister group, Oegopsida. Some of the most obvious differences are found in the structure of the eyes: those of myopsid squids lack a secondary eyelid and are instead covered by a transparent corneal membrane, the opening of which is reduced to a microscopic anterior pore in most species. The arms and tentacles are ornamented with simple suckers (hooks are never present), with additional suckers usually borne on the buccal lappets. The carpal ("wrist") portion of the tentacular club lacks a locking apparatus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bathyteuthida
Bathyteuthida is an order of cephalopods, consisting of small, mesopelagic to bathypelagic squid that in some ways resemble myopsid squid, such as ''Loligo'' and in others the pelagic oegopsid squid. Its two families, the Bathyteuthidae and Chtenopterygidae, each containing a single genus, have previously been included with the oegopsids. As with the oegopsids, the Bathyteuthida lack corneal membranes covering their eyes, something common to myopsid squid, and have paired oviducts, lacking in myopsids. As with the myopsids, bathyteuthids have tentacle pockets in the head and small suckers on the buccal supports, found only in this group, Loliginidae, and Sepiidae; neither is found in true oegopsids. The Bathyteuthida do share the open ocean pelagic habitat with the oegopsid squid, uniting them in that way with that diverse group. The Bathyteuthidae and Chtenopterygidae differ in body conformation, the internal shell, and in the manner in which buccal supports attach to the ...

Cephalopod Beak
All extant taxon, extant cephalopods have a two-part beak, or Rostrum (anatomy), rostrum, situated in the buccal mass and surrounded by the muscular Cephalopod limb, head appendages. The Dorsal (anatomy), dorsal (upper) mandible fits into the ventral (lower) mandible and together they function in a scissor-like fashion.Young, R.E., M. Vecchione & K.M. Mangold (1999)Cephalopoda Glossary Tree of Life Web Project. The beak may also be referred to as the mandibles or jaws.Tanabe, K., Y. Hikida & Y. Iba (2006). Two coleoid jaws from the Upper Cretaceous of Hokkaido, Japan. ''Journal of Paleontology'' 80(1): 138–145. These beaks are different from Beak, bird beaks because they crush bone while most bird beaks do not. Fossilized remains of beaks are known from a number of cephalopod-groups, both extant and extinct, including squids, octopus, octopodes, belemnites, and vampyromorphs. Aptychus, Aptychi - paired plate-like structures found in ammonites - may also have been jaw elements. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glass Squid
The family Cranchiidae comprises the approximately 60 species of glass squid, also known as cockatoo squid, bathyscaphoid squid, cranch squid, or simply cranchiids. The common name "glass squid" derives from the transparent bodies of most species. Cranchiid squid occur in surface and midwater depths of open oceans around the world. Cranchiid squid spend much of their lives in partially sunlit shallow waters, where their transparency provides camouflage. Like most squid, the juveniles of cranchiid squid live in surface waters, descending to deeper waters as they mature. Some species live over 2 km below sea level. The body shape of many species changes drastically between growth stages, and many young examples could be confused for different species altogether. The family ranges in mantle length from to over , in the case of the colossal squid, which is the largest invertebrate alive. The type genus of the family, '' Cranchia'', is named for English naturalist John Cranch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Architeuthidae
The giant squid (''Architeuthis dux'') is a species of deep-ocean dwelling squid in the family Architeuthidae. It can grow to a tremendous size, offering an example of abyssal gigantism: recent estimates put the maximum body size at around for females, with males slightly shorter, from the posterior fins to the tip of its long arms. This makes it longer than the colossal squid at an estimated , but substantially lighter, as it is less robust and its arms make up much of the length. The mantle of the giant squid is about long (longer for females, shorter for males), and the feeding tentacles of the giant squid, concealed in life, are .

Yezoteuthis
''Yezoteuthis'' (" Yezo squid") is an extinct genus of very large oegopsid squid that inhabited the seas around Japan in the Late Cretaceous period. It contains a single species, ''Y. giganteus'' from the early Campanian Osousyunai Formation of the Yezo Group in Hokkaido. It is possibly the largest fossil coleoid ever described. ''Yezoteuthis'' is known from a single upper jaw that shares close similarities with those of oegopsids, hence its assignment to that order. These jaws are very large, and a comparison to modern squid indicates that ''Yezoteuthis'' would have rivalled the extant giant squid (''Architeuthis'') in size, reaching about in mantle length, and more than in total length. ''Yezoteuthis'' was likely a major predator of its ecosystem and existed at a high trophic level. A second set of oegopsid jaws closely resembling those of ''Yezoteuthis'' was described from the Yezo Group in 2023, but was found to be even larger and have different proportions of those fro ...
