Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 6 - 9; Raios dorsais (total) : 12 - 14; Espinhos anais: 1; Raios anais : 14 - 16. Labial ligament to about halfway along premaxilla forming cylindrical pouch lateral to ramus of dentary and just below edge of premaxilla. Premaxilla with ventrally directed tusk-like process. Caudal peduncle very slender. Midlateral scales 40-43; transverse scale rows 7 to 9; interdorsal scales 8-12.
Found close inshore around islands and over coral reefs. Except for larval biology, little is known about this species. It may be taken as food by commercial species. This species is now placed under family Dentatherinidae in Parenti (1984 ?).
