Sclerodactyla briareus

''Sclerodactyla briareus'', commonly known as the hairy sea cucumber, is a species of marine invertebrate in the family Sclerodactylidae. It is found in shallow waters in the west Atlantic Ocean.
==Description==
''Sclerodactyla briareus'' is an elongated oval or cigar-shaped sea cucumber and grows to about . It often adopts a characteristic pose with both ends raised above the substrate. At the anterior end there is a mouth surrounded by a ring of ten, short, branched feeding tentacles.〔In Greek mythology Briareos was one of the multiple-handed giants. Ancient Greek ''skleros'' means hard and "daktylos" means ''finger'': compare Sclerodactyly.〕 These are modified tube feet that can be retracted back into the mouth when the animal is not feeding. The surface of the body is divided into five ambulacral areas with five shallow interambulacral grooves in between. Internally there are five bands of muscle running along the ambulacrae and there are also transverse bands of muscles. Just behind the tentacles is a group of small ossicles, calcareous stiffening plates, forming a short tube surrounding the pharynx. These provide a skeletal support for the muscles and internal organs. The skin is thick and leathery and the tube feet are scattered rather than being in orderly rows, protruding as soft finger-like projections from the body wall.〔(''Sclerodactyla briareus'' ) Invertebrate Anatomy OnLine. Retrieved 2012-02-12.〕 The minute calcareous spicules that are embedded in the skin are characteristic for the species, being square or round and table-shaped with spires formed of four pillars.〔(An illustrated key to the sea cucumbers of the South Atlantic Bight ) Retrieved 2012-02-12.〕 The colour is dark greenish-brown or charcoal grey with pale grey tentacles on blackish stems.〔(''Sclerodactyla briareus'' ) Encyclopedia of Life. Retrieved 2012-02-12.〕
