Actinopterygii (ray-finned fishes) > Perciformes
(Perch-likes) > Pempheridae
Etymology: Pempheris: Greek, pempheris = the name of a fish (Ref. 45335); adusta: Name from Latin 'flavi' meaning yellow, and 'cycla' for ring, referring to the bright yellow ring encircling the pupil, which is often still apparent in recently preserved specimens. More on author: Bleeker.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 0 - 20 m (Ref. 95675). Subtropical
Indo-Pacific: widely distributed and abundant in the Indian Ocean (including the Red Sea to Andaman Sea) to the Pacific; not in the Mediterranean Sea. Regional variations present in the Indian, Andaman and the Pacific.

soft rays: 36 - 45;
Vertebrae: 25. This species is distinguished by the following characters: pectoral fin base with a faint blackish spot; pored lateral-line scales 56-64 (Andaman Sea 52-58; Pacific 51-62); scale rows above lateral line 4.5-6.5 (usually 5.5; Andaman Sea and the Pacific Ocean, 4.5-5.5, usually 4.5); circumpeduncular scales 14-18 (usually 16); outer edge of anal fin with a distinct blackish band (rarely faint or only anterior half prominent; usually none in Pacific); posterior edge of caudal fin with a blackish band (caudal fin whole yellowish in Andaman Sea); upper-jaw length 14.2-15.6% SL; body depth 41.4-45.4% SL. Individuals in the Pacific are distinguished from its congeners by the following set of characters: ctenoid and deciduous scales are thin and semicircular in shape; 51-62 pored lateral-line scales; 4.5-5.5 (usually 4.5) scale rows above lateral line; pectoral fin base with a faint blackish spot; anal fin usually have no blackish outer margin; anal fin base with a dusky band (Ref. 95675).
This fish is common on coral reefs (Ref. 6645); forming aggregations in caves or crevices or under overhangs (Ref. 48636) by day, but a few may at times be seen in the open, close to the shelter of reefs. This species is also observed forming small groups with Myripristis murdjan at 0.5-1 m below the surface. At night, it is known to feed on zooplankton (Ref. 94773). Spawning occur during April to June, and is year-round in Okinawa I. (Koeda et al., in press - in Ref. 95675). Spawning occurred after sunset with individuals larger than 11 cm SL joining the spawning group (Ref. 95675). Flesh is edible (Ref. 12484).
