Holothuria thomasi
''Holothuria thomasi'', the tiger's tail, is a species of sea cucumber in the family Holothuriidae. Although it is the largest sea cucumber known in the western Atlantic Ocean, it is so well camouflaged that it was 1980 before it was first described. It is placed in the subgenus ''Thymiosycia'' making its full name ''Holothuria (Thymiosycia) thomasi''.〔
==Description==
''Holothuria thomasi'' receives its vernacular name from its resemblance to a tiger's tail. It takes the form of an elongated cylinder with rounded ends and can reach long. It is mottled with patches and streaks of dark brown, golden brown and white, sometimes with irregular rings of colour. On the upper side there are papillae, thorn-like projections, which are dark brown tipped with white. The underside is paler and has several longitudinal rows of tube feet. The animal has no eyes and the mouth is at the anterior end surrounded by a fringe of about 20 shield-shaped tentacles. When it is feeding, this end is enlarged. When small, individuals move about freely, but larger ones conceal themselves in crevices or under projections and are seldom seen.〔(Holothuria thomasi ) Smithsonian Tropical Research Institute.
