Asteriidae
The Asteriidae are a diverse family of Asteroidea (sea stars) in the order Forcipulatida. It is one of three families in the order Forcipulatida. The oldest unambiguous fossils of the family date to the Late Cretaceous. Genera The World Register of Marine Species lists these genera within the family Asteriidae (in a field of 6 families): * '' Adelasterias'' Verrill, 1914 * '' Anasterias'' Perrier, 1875 * '' Aphanasterias'' Fisher, 1923 * '' Aphelasterias'' Fisher, 1923 * ''Asterias'' Linnaeus, 1758 * '' Astrometis'' Fisher, 1923 * '' Astrostole'' Fisher, 1923 * '' Caimanaster'' A.M.

Leptasterias Hexactis
''Leptasterias hexactis'' is a species of starfish in the Family (biology), family Asteriidae, commonly known as the six-rayed star. It is found in the intertidal zone of the western seaboard of the United States. It is a Predation, predator and is unusual among starfish in that it Egg incubation, broods its eggs and young. Taxonomy ''Leptasterias hexactis'' forms part of a species complex. Over the years, various authorities have discussed the phylogenetic relationships of ''L. epichlora'', ''L. aequalis'' and ''L. hexactis'', all species of ''Leptasterias'' found in the north west Pacific Ocean. The authorities were Bush (1918), Fisher (1930), Chia (1966), Kwast (1990) and Stickle (1992). More recent morphological and behavioural studies have resulted, according to the World Register of Marine Species (WoRMS) in the retention of a single species, ''L. hexactis'', with the other two being considered synonyms. WoRMS now recognizes three subspecies, ''L. hexactis hexactis'' (Stimp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asterias
''Asterias'' is a genus of the Asteriidae family of sea stars. It includes several of the best-known species of sea stars, including the (Atlantic) common starfish, ''Asterias rubens'', and the northern Pacific seastar, '' Asterias amurensis''. The genus contains a total of eight species in all. All species have five arms and are native to shallow oceanic areas (the littoral zone) of cold to temperate parts of the Holarctic. These starfish have planktonic larvae. ''Asterias amurensis'' is an invasive species in Australia and can in some years become a pest in the Japanese mariculture industry. History The genus ''Asterias'' was first described by Carl Linnaeus in the 10th edition of Systema Naturae in 1758 when he published ''A. rubens''. It was for a time the only species, but by the early 1800s a few dozen taxa had been described in this genus. In 1825 Thomas Say listed six species native to the coasts of the United States (which at the time consisted of the east coast from M ...
