Taxonomic and biological aspects are presented on five species of shallow water holothurians from the Cayos Cochinos Biological Reserve-CCBR located on the northern Honduran shelf, western Caribbean at 16 degrees N, 86 degrees W. This article provides a taxonomic key of the recorded holothurians and morphometric/morphologic descriptions of their corresponding spicules. These five species belong to a single order (Aspidochirotida) and two families: Stichopodidae (Isostichopus badionotus) and Holothuriidae (Holothuria mexicana, H. thomasi, H. arenicola and Actinopyga agassizi). In addition, the commensal pearlfish, Carapus bermudensis is recorded from H. mexicana and A. agassizi.
