Comatuloidea

	Comatuloidea Comatulidae is a family of comatulid crinoids. Since 2015, it replaces the family Comasteridae. Description and characteristics This family is of recent restoration, and still has no consensual description. However the description of the family Comasteridae remains partially valid. This family counts between 93 and 95 species, distributed in 21 genera, which makes it the second most diversified family of crinoids the behind Antedonidae, representing approximately 1/6th of known crinoid species. It contains most of the big species of shallow tropical feather stars, in particular in the Indo-Pacific. List of genera This family has been recently restored following genetic works from Charles Messing's team. It contains the following genera: * sub-family Comatellinae Summers, Messing, Rouse, 2014 genus '' Alloeocomatella'' Messing, 1995 -- 2 species genus '' Comatella'' AH Clark, 1908 -- 2 species genus '' Davidaster'' Hoggett & Rowe, 1986 -- 2 species genus '' N ...

	Articulata (Crinoidea) Articulata are a subclass or superorder within the class Crinoidea, including the only living crinoid species. They are commonly known as sea lilies (stalked crinoids) or feather stars (unstalked crinoids). The Articulata are differentiated from the extinct subclasses by their lack of an anal plate in the adult stage and the presence of an entoneural system. Articulata first appeared in the fossil record during the Triassic period although other, now extinct crinoid groups, originated in the Ordovician. Characteristics Articulata exhibit pentamerous symmetry. The stalk, which consists of numerous disks held together by ligaments, supports a calyx or cup made of circlets of calcerous plates. In Comatulids, the stalk develops following the larval stage, but the juveniles shed all but the topmost disk to take up a free-living existence. Five often branched arms, which consist of articulated series of ossicles, extend from the oral plate and form the food-capture mechanism of Articula ...

	Anneissia Bennetti ''Oxycomanthus bennetti'', the Bennett's feather star, is a species of crinoid belonging to the family Comatulidae. It is found in shallow water in the Indo-Pacific between northern Australia and southeast Asia. Description ''Oxycomanthus bennetti'' is one of the larger species of Comatulidae, growing up to 30 cm. It is a filter-feeder, meaning it does not hunt down food, it captures food suspended in the water column to eat. It does this with 31–120 feathery arms, usually held up into the water in order to trap food, feeding on detritus, phytoplankton and zooplankton. The arms have numerous finger-like appendages known as pinnules, in order to increase the surface area on which food can be trapped. The mouth is on the upper side of the large, thick body, otherwise known as the centrodorsal. Attached to the centrodorsal are many long, robust cirri (3-4.5 cm). These cirri are used by ''O. bennetti'' to hold on to substrate in the beginning portion of their lives, after the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
