Velodona
''Velodona togata'' is a species of octopus in the monotypic genus ''Velodona''. First described by Carl Chun in 1915, with a second subspecies discovered by Guy Coburn Robson in 1924, it was named for the distinctive membranes on its arms. Described as being similar to members of the genera '' Pareledone'', ''Eledone'', and ''Enteroctopus'', ''V. togata'' has a large body with large eyes and extensive membranes that link the octopus' arms together. The species has a single line of suckers on each arm, and its head, mantle, and part of its arms are covered in warts. Although the reproductive habits of ''V. togata'' have not been extensively studied, the species is believed to be one of the most fecund among octopuses in its region and depth level, despite the species possessing large eggs and extremely large spermatophores. The species is found in the Indian Ocean, off the coast of South Africa, Mozambique, and Tanzania. The species has been captured from depths between 400 a ...

Megaleledonidae
Megaleledonidae is a family of octopuses in the Superfamily (taxonomy), 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'' Guy Coburn Robson, Robson, 1932 * ''Graneledone'' Louis Joubin, Joubin, 1918 * ''Megaleledone'' Iw.

Carl Chun
Carl Chun (1 October 1852 – 11 April 1914) was a German marine biologist. Chun was born in Höchst, today a part of Frankfurt, and studied zoology at the University of Leipzig, where from 1878 to 1883 he was privat-docent of zoology and an assistant to Rudolf Leuckart. After professorial posts in Königsberg (1883–1891) and Breslau (1891–1898), he returned to Leipzig as a professor of zoology.UNI Leipzig Professorenkatalog (biographical sketch) In 1888, Chun described seasonal vertical migration (SVM) which has a periodicity of ca. 1 year. Chun examined depth-stratified net samples from the |
Anatomical Terms Of Location
Standard anatomical terms of location are used to unambiguously describe the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal. Additionally, for some animals such as invertebrates, some terms may not have any meaning at all; for example, an animal that is radially symmetrical will have no anterior surface, but can still have a description that a part is close to the middle ("proximal") or further from the middle ("distal"). International organisations have determined vocabularies that are often used as standard vocabularies for subdisciplines o ...

Eledone Massyae
''Eledone massyae'', the combed octopus, is a small benthic octopus found off the Atlantic coasts of southern South America, particularly Argentina and southern Brazil. Description The body is rounded and slightly flattened dorso-ventrally. The head is narrower than the mantle and separated by a slight constriction. The opening in the mantle is very large and the arms are the same length. The suckers are small, separated from one another and deeply anchored in the arm. The third arm possesses a hypocotyl in the male individuals. Also in males, other arms have suckers that decrease in number until the tip of the arm. After the last sucker are two ranges of papillae that diverge on the sides. On female individuals, the arms are not modified. Females have a variable size ranging from 24 to 91 mm and males vary between 22 to 80 mm. ''Eledone massyae'' feeds mostly on macro crustaceans such as crabs from the Portunidae family as well as polychaetes and mullusks. Distributio ...

Enteroctopodidae
Enteroctopodidae is a small family of octopuses.

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'').

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia l ...

Siphon (mollusc)
A siphon is an anatomical structure which is part of the body of aquatic molluscs in three classes: Gastropoda, Bivalvia and Cephalopoda (members of these classes include saltwater and freshwater snails, clams, octopus, squid and relatives). Siphons in molluscs are tube-like structures in which water (or, more rarely, air) flows. The water flow is used for one or more purposes such as locomotion, feeding, respiration, and reproduction. The siphon is part of the mantle of the mollusc, and the water flow is directed to (or from) the mantle cavity. A single siphon occurs in some gastropods. In those bivalves which have siphons, the siphons are paired. In cephalopods, there is a single siphon or funnel which is known as a hyponome. In gastropods In some (but not all) sea snails, marine gastropod molluscs, the animal has an anterior extension of the mantle called a siphon, or inhalant siphon, through which water is drawn into the mantle cavity and over the gill for r ...

Hectocotylus
A hectocotylus (plural: ''hectocotyli'') is one of the arms of male cephalopod A cephalopod is any member of the molluscan class Cephalopoda ( Greek plural , ; "head-feet") such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, ...s that is specialized to store and transfer spermatophores to the female. Structurally, hectocotyli are muscular hydrostats. Depending on the species, the male may use it merely as a conduit to the female, analogously to a penis in other animals, or he may Autotomy, wrench it off and present it to the female. The hectocotyl arm was first described in Aristotle's biology, Aristotle's biological works. Although Aristotle knew of its use in mating, he was doubtful that a tentacle could deliver sperm. The name ''hectocotylus'' was devised by Georges Cuvier, who first found one embedded in the mantle of a female Argonaut (animal), argonaut. Supposing it to be ...
