Distribution. Members of the genus Phascolosoma are found in burrows, crevices or sandy pockets in rocky, shallow warm waters. Phascolosoma perlucens has a circumtropical distribution including the Caribbean from Florida ( USA) to Venezuela, as well as both sides of the Pacific and the Indian Oceans ( Cutler, 1994). Rice (1975) collected P. perlucens from sites on Margarita Island, Cubagua Island and Los Totumos in Venezuela and Piscadera Baai and Spaansche Water in Curaçao.
