Starspotted Grouper

Epinephelus hexagonatus, commonly referred to as the star-spotted groper or the wirenet rockcod, is a species of ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found mostly in the West Indian Ocean. It is named after the polygonal pattern of brown spots on its skin. There is a white triangle between each spot, and five darker spot clusters along the base of the dorsal fin. The colouration of this fish provides camouflage in the reefs.
