Description
The black grunt is a grunt of the family Haemulidae from the western Atlantic and Caribbean. The species grows to about 40 cm and has a silvery body with oblique dark dashes along the scale rows and dark fins. It inhabits shallow coastal waters over mud to sand bottoms and is less common in clear water with coral. By day it often gathers in schools; at night it forages on the bottom on small crustaceans, worms and molluscs. Grunts make a grunting sound with the pharyngeal teeth, amplified by the swim bladder. The species is a valued food fish and harmless to humans.
