Scarus spinus, the Greensnout parrotfish, is a species of marine ray-finned fish, a parrotfish from the family Scaridae.[2][3][4]
Description[edit]
Scarus spinus can reach a total length of about 30 cm (in males).[4] These fishes have 10 dorsal soft rays, 3 anal spines and 9 anal soft rays. Males show a bright yellow head underwater, while females are drab with white teeth and some pale spots. Caudal fin is moderately to deeply emarginate in terminal phase. Lips largely cover dental plates.[4]
Distribution and habitat[edit]
This species can be found on Christmas Island and from the Philippines to Samoa, the Ryukyu Islands and the southern Great Barrier Reef. The Greensnout parrotfish inhabits coral-rich areas of outer lagoon and seaward reefs, at a depth range 0 - 30 m.[4]
Biology[edit]
It appears specialized in scraping crustose coralline algae with its jaw.[5] It can change gender from female to male (hermaphroditic).[6]
