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.

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 ...

''Adelieledone'' is a genus of octopuses in the family 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. Reproduc .... According to the Census of Marine Life, it may be the closest living relative of the Antarctic ancestor of all octopus species that lived 30 million years ago. Their habitats include; Southern Ocean, Antarctic Ocean, and South Georgia. The most notable feature of adelieledone is the rostral point on the lower beak. It is placed in the family Megaleledonidae by some authorities and in the Octopodidae by others.

Octopus
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 earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Praealtus
''Praealtus paralbida'' is a species of octopus in the family Megaleledonidae. It is the only known species in the monotypic genus ''Praealtus''. It is very similar to '' Bentheledone albida'', a taxon that is considered a ''nomen dubium''; its true taxonomic status will not be confirmed until more specimens are collected. It reaches a total length of 380mm, with a round mantle and narrow head and medium length arms each with a single row of suckers.

Microeledone
''Microeledone mangoldi'', the sickle-tooth pygmy octopus, is a species of octopus from the family Megaleledonidae. This species was described in 2004, the type specimen being a male which was collected from a depth of approximately near the Norfolk Ridge, in the southwest Pacific Ocean near New Caledonia. It is a very small octopus which has a single row of suckers, lacks an ink sac and has a radula with seven rows of teeth with the unique central tooth, called the rechidian tooth, being curved with a grooved tip. The remaining teeth are flat and plate like and so are also distinctive. The smooth creamy-pink body lacks any chromatophores. The specific name honours the Swiss malacologist and marine biologist Katharina Mangold-Wirz Katharina Maria Mangold-Wirz, née Wirz, (born Basel 23 May 1922 - died Basel 22 November 2003) was a Swiss marine biologist and malacologist, who worked at Université Pierre et Marie Curie's Laboratoire Arago in Banyuls-sur-Mer, France.

Vosseledone
''Vosseledone charrua'', the Charrua octopus, is a species of octopus, the only species in the monotypic genus ''Vosselodeone'', in the family Megaleledonidae. It was described by Francisco J. Palacio in 1978 from specimens collected off southern South America in the South Atlantic Ocean. It was distinguished from closely related taxa by its well developed ink sac and its degenerate radula The radula (, ; plural radulae or radulas) is an anatomical structure used by molluscs for feeding, sometimes compared to a tongue. It is a minutely toothed, chitinous ribbon, which is typically used for scraping or cutting food before the food .... It appears to be restricted to consolidated substrates made up of relict corals.
