Enteroctopodidae
Enteroctopodidae is a small family of octopuses. This family was formerly considered a subfamily of the family Octopodidae ''sensu lato'' but this family has now been divided into a number of separate families with Enteroctopodidae as one of them. Genera These genera are included in the family Enteroctopodidae: * ''Enteroctopus'' Rochebrune & Mabille, 1889 * ''Muusoctopus ''Muusoctopus'' is a cosmopolitan genus of deep-sea octopus from the family Enteroctopodidae.

Muusoctopus
''Muusoctopus'' is a cosmopolitan genus of deep-sea octopus from the family Enteroctopodidae. These are small to medium-sized octopuses which lack an ink sac. Recent work has suggested that these octopuses originated in the North Atlantic and subsequently moved into the North Pacific 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 the definition, to Antarctica in the south, and is bounded by the contine ... while the species in the Southern Hemisphere are descended from multiple invasions from northern oceans. Reproductive These octopus species are known to spawn a single batch of eggs instead of producing batches of them over time. As much as these octopuses may release eggs simultaneously or in batches in an extremely short period, they are mostly not prolific spawners. Species These species are currently classified as members of the genus ''Muusoct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sasakiopus
''Sasakiopus'' is a genus of octopus containing only one species, ''Sasakiopus salebrosus'', the rough octopus. It is part of the family Enteroctopodidae. Genetic analysis appeared to show that ''S. salebrosus'' is the sister taxon of the genera '' Benthoctopus'' and '' Vulcanoctopus'', although the former is now considered a synonym of '' Bathypolypus'', the only genus in the family Bathypolypodidae, and the latter as a synonym of ''Muusoctopus''. The type specimen was collected and the Sea of Okhotsk, and the describer Madoka Sasaki named it ''Octopus salebrosus'' in 1920. When Guy Coburn Robson revised the Octopodidae, he tentatively reassigned ''O. salebrosus'' to ''Bathypolypus'' based on its rough skin, deep web, and short arms. The only specimens available to Robson were females, so the ligula could not be examined, the ligulae of ''Bathypolypus'' are distinctively large and are laminated. Subsequent workers raised doubts about where this species should be placed until ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Octopus
An octopus (: octopuses or octopodes) 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 centre point of the eight limbs. An octopus can radically deform its shape, enabling it to squeeze through small gaps. They trail their appendages behind them as they swim. The siphon is used for respiration and locomotion (by water jet propulsion). Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse invertebrates. Octopuses inhabit various ocean habitats, 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, and are short-lived. In most species, the male uses a speciall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enteroctopus
''Enteroctopus'' is an octopus genus whose members are sometimes known as giant octopuses. Etymology The generic name ''Enteroctopus'' was created by Alphonse Tremeau de Rochebrune and Jules François Mabille in 1887 and published in 1889, joining Ancient Greek 'gut' and , thus 'octopus ith arms similar toguts.' Description ''Enteroctopus'' is a genus of generally temperate octopuses. Members of this genus are characterized by their large size and are often known as giant octopuses. ''Enteroctopus'' species have distinct longitudinal wrinkles or folds dorsally and laterally on their bodies. Their heads are distinctly narrower than the mantle width. The hectocotylus of the males in this genus, found on the third right arm, is long and narrow in comparison with other genera in the family Octopodidae, often comprising one-fifth the length of the arm. Octopuses in this genus have large, paddle-like papillae instead of the more conical papillae in other octopus genera. Spe ...

Vulcanoctopus
''Vulcanoctopus hydrothermalis'', also known as the vent octopus, is a small benthic octopus endemic to hydrothermal vents. It is the only known species of the genus ''Vulcanoctopus''. This vent octopus is endemic to the hydrothermal vent habitat that is located in the East Pacific Rise. ''V. hydrothermalis'' has evolved unique adaptations to accommodate for the distinct circumstances of this very dynamic habitat. In particular, they are characterized as having double rows of suckers on each arm. ''V. hydrothermalis'' has been shown to exhibit feeding that relies on the coordination of their arms to entrap their prey. In terms of external appearance, both the female and male vent octopuses exhibit similar physical traits. Internally, the anatomy of the reproductive and digestive tract is different between female and male vent octopuses. Habitat ''Vulcanoctopus hydrothermalis'' lives along the East Pacific Rise which borders the Pacific, Cocos, and Nazca Plates. The vent oct ...

Enteroctopus Zealandicus
''Enteroctopus zealandicus'', the yellow octopus, is a large octopus of the genus ''Enteroctopus''. It is endemic to the waters surrounding New Zealand. Description ''Enteroctopus zealandicus'' has the distinctive characteristics of the genus ''Enteroctopus'', including longitudinal folds on the body and large paddle-like papillae. ''E. zealandicus'' is a large octopus, reaching a total length of at least , though few whole samples have been collected and this is only a guide. Range and habitat ''Enteroctopus zealandicus'' is endemic to New Zealand. Samples have been collected along the east coast of the south island, Chatham Rise, Campbell Plateau, Stewart, Auckland and Antipodes Islands; and from the surface down to depth. There is an absence of published information about the preferred habitat or diet of this species. Predators ''Enteroctopus zealandicus'' is one of the most important prey of New Zealand sea lions at the Auckland Islands and Campbell Island, in t ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Subfamily
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end botanical subfamily names with "-oideae", and zoological subfamily names with "-inae". Detarioideae is an example of a botanical subfamily. Detarioideae is a subdivision of the family Fabaceae (legumes), containing 84 genera. Stevardiinae is an example of a zoological subfamily. Stevardiinae is a large subdivision of the family Characidae, a diverse clade In biology, a clade (), also known as a Monophyly, monophyletic group or natural group, is a group of organisms that is composed of a common ancestor and all of its descendants. Clades are the fundamental unit of cladistics, a modern approach t ... of freshwater fish.
