Genus: ,

Scientific Name: Chlorurus capistratoides

English Name: Indian/Pink-margined parrotfish

Creole Name: Kakatwa (Initial Phase: "Lamouta")

French Name:

IUCN Red List Status: Least Concern (LC)

Description:

2 rows of scales on cheek, (upper with 6 or 7, lower with 6-8 scales). Dental plates broadly exposed with 1-3 posteriorly inclined canine teeth on side at rear of upper dental plate. Head bluntly rounded in profile. Initial phase Caudal fin of initial phase slightly rounded; truncate to slightly emarginate in Terminal phase.
This species exhibits a complex colour pattern that is summarised here with a detailed description, derived from Randall & Bruce (1983), below.
Initial phase: reddish brown body with 4-5 pale bars on flank, snout paler red, yellow pectoral fins, Dorsal fin yellowish with blue-grey margin and median stripe. Caudal fin pale red/pink. 
Terminal phase: Blue green body with pink bars on each scale, broad pink band on operculum, blue green bands on head and pale caudal fin. 

Detailed description
Initial phase: body reddish brown with a brownish orange bar on each scale anteriorly, the bars becoming shorter posteriorly, ultimately forming spots on caudal peduncle; 4 pale pinkish bars on body, the scales in the bars retaining their brownish-orange bars; rear half of caudal peduncle and all of caudal fin pale salmon-pink; head reddish brown, the snout and diffuse broad bands radiating from eye light brownish-red; dental plates pinkish white; dorsal fin dull orange with a bluish grey margin and median longitudinal band; anal fin brown with bluish grey margin; pectoral fin rays yellow becoming brown basally, the membranes pale, the base brownish red; pelvic fins brown.
Terminal phase: body blue-green with a salmon pink bar on each scale, bars shortening posteriorly to oval spots on caudal peduncle. Abdomen and thorax pale blue-green, becoming pale salmon ventrally; head blue-green dorsally with narrow blue-green bands as follows: one dorsally on upper lip to corner of mouth, thence almost to eye where it passes horizontally under eye to opercular flap, then angling ventrally submarginal to edge of operculum; a second band from snout in front of upper edge of orbit, through dorsal part of eye and extending dorsoposteriorly; an irregular third band extending posteriorly from behind centre of eye. Blue-green band across chin to behind mouth. Cheek below horizontal blue-green band abruptly pale salmon-pink; dental plates white with a faint lavender cast; dorsal and anal fins salmon to yellowish with broad turquoise borders and a narrow turquoise band at base; caudal fin salmon with turquoise upper and lower borders and a broad crescentic light blue posterior border; pectoral fins with upper edge bluish, then a broad zone of salmon faintly streaked with dusky purplish, becoming pale on lower half of fin; pelvic fins with light salmon to yellowish rays and pale membranes, the lateral margin faintly light bluish.
 


Size:

Maturity: Lm unknown. Range unknown. Max Length: 40 cm TL.


Habitat and Ecology:

Inner and coastal reefs (depth 2-20m) favouring coral and algal habitats.

Females form small groups. Oviparous, distinct pairing during breeding.


Fishery Status:

This species is not protected or subject to fishery regulations. It is caught in the fish trap fishery, but is a relatively uncommon component of the catch. Catch monitoring indicates the species is more common around certain more isolated islands on the Mahe Plateau.


Notes:

Very similar in appearance to Chlorurus atriluna which has also been cited as occurring in Seychelles (Bruce & Randall 1984) but has yet to be noted in the artisanal catch in a 2013-2019 survey – J. Nevill pers comm. The Initial phase for both species is very similar but front of snout of C. atriluna is solid brownish red. The Terminal phase of C. atriluna has a black crescent on the caudal fin.
