An intricate pattern of spots, blotches and bars decorates the robust body of the epaulet grouper. With the exception of the underside, the anterior half of its yellowish-grey body (including the head) is covered in numerous orange-red or reddish-brown spots. In contrast, several alternating, light-and-dark, vertical bars extend backwards from around the middle of the body to the caudal fin(2)(3). In common with many other groupers, the mouth is large, and the long dorsal fin is divided into a conspicuously spiny portion followed by a soft portion (4).
Other than its apparent habitat preferences, almost nothing is known about the biology of the epaulet grouper (1). However, like other Epinephelus species, it is probably a protogynous hermaphrodite, meaning that individuals begin mature life as female and change sex later to become male (2)(3). Epinephelus species tend to be voracious predators, with fish and crustaceans taken near the sea bottom forming the bulk of prey (2)(5).
Although the epaulet grouper is caught in traditional fisheries in parts of its range, there is no published fisheries information available. Nonetheless, this species is not thought to be currently threatened (1).
Diverse group of arthropods (a phylum of animals with jointed limbs and a hard chitinous exoskeleton) characterised by the possession of two pairs of antennae, one pair of mandibles (parts of the mouthparts used for handling and processing food) and two pairs of maxillae (appendages used in eating, which are located behind the mandibles). Includes crabs, lobsters, shrimps, slaters, woodlice and barnacles.
The unpaired fin found on the back of the body of fish, or the raised structure on the back of most cetaceans.
An animal that begins its life cycle as a female. As the animal ages, based on internal or external triggers, it shifts sex to become a male animal.
