Showing details for the adult stage. Switch stages to see how it differs.

01

Overview

Found singly or in small schools, hovering in mid-water over channels and reef slopes, of outer reefs.

Groupers are solitary carnivores that hunt near the bottom usually at dusk. Food is drawn into their mouths by a powerful suction when they open their overly large mouths and then swallowed whole.
Spawning is seasonal and controlled by the moons phase.
