Sea Fan
Alcyonacea, or soft corals, are an order of corals. In addition to the fleshy soft corals, the order Alcyonacea now contains all species previously known as "gorgonian corals", that produce a more or less hard skeleton, though quite different from "true" corals (Scleractinia). These can be found in suborders Holaxonia, Scleraxonia, and Stolonifera. They are sessile colonial cnidarians that are found throughout the oceans of the world, especially in the deep sea, polar waters, tropics and subtropics. Common names for subsets of this order are sea fans and sea whips; others are similar to the sea pens of related order Pennatulacea. Individual tiny polyps form colonies that are normally erect, flattened, branching, and reminiscent of a fan. Others may be whiplike, bushy, or even encrusting. A colony can be several feet high and across, but only a few inches thick. They may be brightly coloured, often purple, red, or yellow. Photosynthetic gorgonians can be successfully kept in ...

Agelas Flabelliformis
''Agelas flabelliformis'', also known as the elephant ear sponge, is a species of demosponge. It takes the form of a large leathery slender flap and is found in the Caribbean area at depths down to . Description The elephant ear sponge consists of a large thin flap of spongy material attached edgewise to the substrate by a short peduncle or stem about in diameter. It is usually less than thick but may reach a height and width of a metre (yard) or so. There is often a central lobe with two side flaps. The consistency is firm and leathery but also fragile. On one side it has many large, circular osculi (holes) scattered across the surface. On the other side are small pores and a few, widely dispersed, irregular osculi and some groups of smaller ones. Each vent is surrounded by a collar or rim of thickened skin. The tissue forming the sponge is strengthened by the incorporation of a single type of mineralised spicule. These spicules are classified as acanthostyles and consist of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Agelas Dispar
''Agelas dispar'' is a species of demosponge in the family Agelasidae. It lives on shallow-water reefs in the Caribbean Sea and around the West Indies. Taxonomy ''Agelas dispar'' is the type species of the genus and was first described in 1864 by the French naturalist Édouard Placide Duchassaing de Fontbressin and the Italian naturalist Giovanni Michelotti. They deposited the holotype in Amsterdam. In 1932, the zoologists M. Burton and H.S. Rao, unaware that the holotype was still in existence, deposited a neotype in the Natural History Museum in London, but this specimen has since disappeared. Description ''Agelas dispar'' forms massive irregularly-shaped, sometimes bulbous mounds or may be encrusting. It can grow to as much as across. The consistency is spongy but firm; the surface is smooth with many exhalent pores of irregular shape and size, often in shallow pits. The colour externally is pinkish-brown, reddish-brown or deep brown. Internally there are large cavities, man ...
