Jewfish are a type of grouper. They are large fish with a large, broad, flat head and mouth. They are often spotted or dark in color, but are capable of changing color in order to camouflage. Common around wrecks and pilings. Young hatch at up to 45 cm in size and are more yellowish in color than the adults to assist in camouflage.
Groupers begin life as females, and can lay eggs.
After 7-10 years groupers become male. Lifespan is unknown. Predators are sharks. Nocturnal and shy creatures, green morays often hide in crevices and coral. Their dorsal, caudal and tail fins are joined as one long fin down their back and up their belly.
