	Actinostella Flosculifera ''Actinostella flosculifera'', the collared sand anemone, is a species of sea anemone in the family Actiniidae. It is found semi-immersed in the sediment in shallow water in the tropical and subtropical Atlantic Ocean. Description The only part of this sea anemone that is normally visible is the oral disc, which lies flat on the seabed, the tall cylindrical column being immersed in sediment. The column is cream or pink and the upper part bears sticky warts to which pieces of gravel and fragments of shell adhere. The oral disc is up to in diameter and bears four whorls of pointed, retractable tentacles close to the funnel-shaped mouth, the outer tentacles being shorter than the inner ones. The outer part of the disc resembles a collar or ruff, and bears irregular fleshy tubercles perforated by fine pores, and separated by slender radial lines. The disc is beige, pinkish, brown or grey, sometimes with some green banding, and blends well with the surrounding sediment in colour and ...

	Actiniidae Actiniidae is the largest family of sea anemones, to which most common, temperate, shore species belong. Most members of this family do not participate in symbioses with fishes. Three exceptions are the bubble-tip anemone (with anemonefish and certain cardinalfish), snakelocks anemone (with Incognito goby) and '' Urticina piscivora'' (with painted greenling). The systematics of Actiniidae is often quite difficult. The problem with identification of genera within this family is that most species are readily distinguishable when alive but when fixated lose their color and some other features. Arrangement of tentacles is important in defining genera for Actiniaria families. There may be one tentacle per space between mesenteries or there may be more than one tentacle between each two mesenteries. Members of the family Actiniidae have one tentacle per space. Genera Genera in this family include: * ''Actinia'' Linnaeus, 1767 * '' Actinioides'' Haddon & Shackleton, 1893 * '' Acti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Genus Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should cl ...
