Dorsale stekels (totaal) : 6 - 9; Dorsale zachte stralen (totaal) : 12 - 14; Anale stekels: 1; Anale zachte stralen: 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.
Body shape (shape guide): elongated; Cross section: oval.
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 ?).
