TAXONOMY
Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Perciformes
Family: Scaridae
Genus/species: Scarus quoyi
GENERAL CHARACTERISTICS: Parrotfishes are wrasse-shaped but more heavy-bodied. The main difference is the structure of their mouth. Wrasses have individual teeth, but parrot fish teeth are actually fused together, forming a beak.
Mature males are blue-green with pinkish scale margins. The operculum is orange dorsally and violet ventrally. There is a patch of blue-green on the cheek and across the snout. – female Greenblotch Parrotfish are pale grey-brown with five or six faint white bars on the body.
Length up to 28 cm.
DISTRIBUTION/HABITAT: Found from the Maldives to Vanuatu, extending northwards to Ryukyu Islands, Japan and southwards to New Caledonia inhabiting coral-rich areas of outer channels and seaward reefs.
DIET IN THE WILD: Herbivorous, feeds on algae from rocky substrates.
REPRODUCTION: Parrotfishes are pelagic spawners. They release buoyant eggs which become part of the plankton floating freely, eventually settling into the coral until hatching.
CONSERVATION: IUCN Least Concern (LC)
REMARKS: A recent study has discovered that the parrotfish is extremely important for the health of the Great Barrier Reef. It is the only one of thousands of reef fish species that regularly performs the task of scraping and cleaning inshore coral reefs.
Note: S. quoyi does not feed on coral algae thus does not destroy coral , which is why it can be present in the Philippine coral reef exhibit exhibit. (Charles Delbeek M.Sc. Assistant Curator, Steinhart Aquarium California Academy of Sciences)
