Description

The javelin grunter is a grunt of the family Haemulidae from the Indo-West Pacific. The species grows to about 80 cm and has a silvery body, in juveniles with rows of dark spots. It inhabits turbid coastal waters with sandy to muddy bottoms to about 75 metres and enters estuaries, tolerating low salinity. As a bottom predator it feeds on crustaceans, molluscs, worms and small fishes. Grunts make a grunting sound with the pharyngeal teeth, amplified by the swim bladder. The javelin grunter is a valued food fish and harmless to humans.
