Groupers are large and important predators on coral reefs. They help to maintain the health of a reef by picking off weak fish. They also eat crabs and spiny lobsters. The potato grouper inhabits deeper reef channels and seamounts. It has a large head and heavy body with a single long, spiny dorsal fin. Irregular dark streaks radiate from the eyes. These fish are territorial and in some areas, individuals are hand-fed by divers. However, one diver drowned after being rammed in the chest by a large potato grouper. The large size of these fish makes them an easy target for spearfishermen.
