Korte beschrijving
Determinatiesleutels | Morfologie | Morfometrie
Dorsale stekels (totaal) : 3; Dorsale zachte stralen (totaal) : 29; Anale zachte stralen: 25; Wervels: 18. This species is distinguished by the following characters: 3 pigmented cheek grooves; low body scale rows count 34 (33-35) vs. 39 or more; small size, 15.4 cm SL vs. over 22.5 cm SL; and a colour pattern of scattered dark spots sub-dorsally and without other spots or line on the body.
This species is relatively abundant within its depth range, on coral rubble and holes adjacent to deeper drop-offs (below a thermocline) at several localities of the coasts of Kiritimati (Christmas Island). It has always been observed near the reef substratum, where it would seek shelter when approached (Ref. 94129).
