Scientific name : Priacanthus hamrur
Family : Priacanthidae
Size : Up to 45 cm
Distribution : Indian Ocean and tropical Pacific
Biology : The lunar-tailed bigeye likes the dark. It hides in groups under overhangs during the day and emerges from its hiding place at dusk.
Its large eyes make it an excellent nocturnal hunter.
Its intense red color allows it to be stealthy in the dark, as red light penetrates very little water.
IUCN status : Least concern
