Marine, fresh- and brackish water. Distribution: most tropical seas. No teeth on vomer and palatine. Rounded caudal fin. Head triangular. Anal and soft dorsal with a rounded lobe posteriorly making the fish look triple-tailed. Juveniles are said to float sideways like leaves as a form of camouflage. To about 1 m maximum length, reported for Lobotes surinamensis. Genera: Datnioides and Lobotes, the former in fresh- and brackish water; the latter marine. Species: about 4. Roberts (1994) proposes the family Coiidae (also known as Datnioididae) for its single genus Coius, formerly known as Datnioides.
