More Info


Distribution

Known in Australia from Cape York to Moreton Bay, Queensland; also Lord Howe Island in the Tasman Sea. Elsewhere the species occurs in the tropical and subtropical, Indo-west-central Pacific.

Inhabits coastal and offshore reefs, aggregating around large coral bommies, often finding shelter in caves, crevices and under ledges during the day.

Features

Dorsal fin VI, 9; Anal fin III, 35-42; 
Pectoral fin 16-18; Lateral-line scales 46-55; Scales above lateral-line 3-4; Gill rakers 25-30.

Scales on sides cycloid, deciduous (lateral-line scales less); body depth 2.35–2.45 in SL; head length 3.2–3.3 in SL; snout length 4.6–5.1 in head length; eye large, 7.2–7.7 in SL; caudal fin length 3.3–4.5 in SL, and moderately to strongly forked, the caudal concavity 2.3–2.55 in head length; pectoral fins 3.2–3.5 in SL; prepelvic length 2.45–2.6 in SL; pelvic fins 1.8–2.05 in head length.

Colour

Variable in colour, often silvery-grey above, with a lavender iridescence, silvery sides, sometimes with coppery scale margins; a black spot on about outer third of dorsal fin, the leading edge broadly blackish; anal fin with a broad blackish band along base; about outer fourth of caudal fin blackish, the upper and lower margins blackish but about half as broad; pectoral fins with a dark bluish grey band across base.

Feeding

A nocturnal species, schooling in caves and crevices during the day, emerging to feed on zooplankton in open water at night.

Remarks

Koeda et al. (2014) suggest that specimens from Western Australia that have previously been identified Pempheris schwenkii are actuallyTominaga's Sweeper, Pempheris tominagai. However, The distributions of the two species do not overlap according to Randall et al. (2014) who suggested that P. tominagai is a Red Sea endemic. Although they did not discuss Australian material, they implied that it might be P. schwenkii
