How to tell it apart

This is the only grunt species in the Caribbean with two black bars crossing its yellow stripes - no other grunt shares that pattern.

Appearance

This fish has a deep, flattened body with a high back and a short, blunt head. Its mouth sits low and horizontal, with fleshy lips. The flanks show alternating yellow and silvery-blue stripes, yellow fins, and a deeply forked tail. A black bar runs diagonally from above the eye to the upper lip, and a second black bar runs from the front of the dorsal fin down to the base of the pectoral fin. Juveniles look different: no black bars, but two black stripes along the middle of the body, a black blotch near the tail base, and a bright yellow head.

Habitat

Lives on reefs and rocky bottoms in shallow water from Florida and the Bahamas through the Caribbean to Brazil, at depths of about 2 to 20 metres. It is active at night and often moves in large schools, sometimes alongside white grunts, while juveniles shelter in beds of seagrass.

Did you know?

Young porkfish work as cleaners, picking parasites off the skin and scales of other fish before they grow into striped adults.
