Common Name: Goldblotch grouper

Scientific Names: Epinephelus costae

Description: A large Grouper 50cm +. It has the typical grouper shape with a strong triangular head, jutting lower jaw and large eyes, but it is much less heavily built than the Dusky grouper (24), with a thinner body. The distinctive dark lines running along the body also distinguishes it from the Dusky grouper. A golden blotch behind the head gives it its name but whilst sometimes obvious, this is only reliably clear in breeding males.

Distinctive Features: This large grouper characteristically has 6 or 7 dark lines running along its body.

Abundance: Solitary or in small groups of 3-5. Seen mainly by divers, perhaps on every other dive.

Habitat & Behaviour: Although it can be seen resting on the seabed it usually swims actively in mid water or adjacent to reefs. It is a predator of smaller fish and seabed life.

Reaction to Snorkellers & Divers: Snorkellers will not see this species at all frequently, but it can be inquisitive of divers and may pose for them.

Other Names: Golden grouper. Some older books call this Epinephelus alexandrinus.
