Scarus spinus, the Greensnout parrotfish, is a species of marine ray-finned fish, a parrotfish from the family Labridae.[2][3]
Description
[edit]
Scarus spinus can reach a total length of about 30 cm (in males).[3] 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.[3]
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.[3]
Biology
[edit]It appears specialized in scraping crustose coralline algae with its jaw.[4] It can change gender from female to male (hermaphroditic).[5]
