Description

The flowery flounder is a striking left-eyed flatfish of the family Bothidae from the Indo-West Pacific. The species reaches about 51 cm; both eyes lie on the left side and in the male are set far apart. The eyed side is brown with numerous blue rings and spots reminiscent of flowers, and the fish can change colour rapidly to blend with the substrate. Males have a strongly elongated pectoral ray. It inhabits sandy bottoms of shallow coral reefs and hunts mainly at night, but also by day, for fishes, crabs and shrimps.
