Caudal rays: principal (10+8-9), procurrent (upper:8, lower: 8) Branchiostegal rays: 23-35

Biology     Glossary (e.g. epibenthic)

Occur in schools in shallow inshore areas. Penetrate lagoons and estuaries (Ref. 9297). Feed on fish and penaeids (Ref. 50313). Spawning probably occur in the open sea and the transparent larvae migrate towards coastal areas (Ref. 9297). Struggle vigorously when caught on hooks and lines (Ref. 9297). Low commercial value due its numerous spines (Ref. 9297).
