IUCN Red List Status: Not Evaluated (NE)
Description:
Dorsal spines: 3; Dorsal rays: 25-27; Anal rays: 24-25.
Greyish to greenish brown dorsally, with small pale spots. Whitish ventrally with yellow spots that can coalesce to form a reticulum particularly posteriorly. 3 large
oval white spots along the back and a small one dorsally on caudal peduncle; a broad white streak often on side of body posterior to upper end of gill opening. White
blotches and mid-lateral stripe can disappear with growth. An oblique groove before the eye; large bony scales behind gill opening. Caudal peduncle depressed, slender
and tapering. Yellow bands on dorsal and anal fins. Caudal fin, yellow with white bars and stripes pattern and diffuse black margin, double emarginate, lobes longer

Size:
Maturity: Lm unknown. Range unknown. Max Length: 60cm TL
Habitat and Ecology:
Reef associated. Inhabits mud and silt sand bottoms (depth 7-350m), usually 7-100m depth on sand, sponge, and weed bottoms. Feeds on benthic animals, including crabs,
molluscs and sea urchins. Juveniles in sheltered coastal bays and estuaries.
Fishery Status:
This species is not protected or subject to fishery regulations. It is caught in both the fish trap and hand line fisheries and is, along with Sufflamen fraenatum,
the most commonly caught triggerfish in the artisanal fishery.
Notes:

Description:
Dorsal spines: 13; Dorsal rays: 12-13; Anal spines: 2; Anal rays: 11-13.
Moderately-full bodied to slender damselfish.
Juveniles are a brilliant blue becoming dull bluish grey with growth.
Size:
Maturity: Lm unknown. Range unknown. Max Length: 11.5 cm TL.
Habitat and Ecology:
Adults occur among rubble or consolidated reef rock of exposed intertidal reef flats and sandy beaches, subject to mild surge. Also near freshwater run-offs. They occur in small groups. Feed mainly on benthic algae. Oviparous, distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Males guard and aerate the eggs. Specimens photo’d here were observed in shallow sandy substrate rockpools, adjacent to a freshwater outlet.
Fishery Status:
This species is not protected or subject to fishery regulations. It is not caught in the artisanal fishery.
