Cetoscarus bicolor

Cetoscarus bicolor

Cetoscarus bicolor, the bicolour parrotfish, is a species of fish from reefs in the Indo-Pacific. It is monotypic within the genus Cetoscarus, although it has been suggested that the scientific name C. bicolor should be reserved for the population in the Red Sea, in which case the remaining populations are named C. ocellatus.[1] It is among the largest parrotfishes, growing to a length of up to 90 centimetres (35 in). As in many of its relatives, it is a sequential hermaphrodite, starting as female (known as the initial phase) and then changing to male (the terminal phase). The initial phase is dark brown with a large cream patch on the upper part of the body. The terminal phase is very colourful, overall green with pink spotting to the body and edging to the fins. Juveniles are white with a black spot on the dorsal fin and an orange band through the eye.
