Groupers
age groupers
Adult Nassau Groupers generally eat a diet of mainly fish (parrotfish, wrasses, damselfish, squirrelfish, snapper and grunts). Juveniles, on the other hand, eat a diet composed mainly of crustaceans (crab, stomatopod, hermit crab, panulirid lobster, and caridean and panaid shrimp). These juvenile groupers are usually found around coral clumps covered with macroalgae and over sea grass beds.

Groupers reproduce by external fertilization, where females release eggs into the water and males release sperm to fertilize them. This usually occurs during spawning events where groupers gather in groups. After fertilization, the eggs develop into larvae that drift in the water until they settle on the ocean floor and grow into juvenile groupers.
