Korte beschrijving Morfologie | Morfometrie

Dorsale stekels (totaal): 11; Dorsale zachte stralen (totaal): 16-18; Anale stekels 3; Anale zachte stralen: 10 - 12. Distinguished by the following characteristics: Tan to brown above, paler below; upper parts of head and most of body usually have small, brown, close-set spots; sometimes uniformly brown. Adults have exerted rays that are even and about equal in length; 23-27 total gill rakers (Ref. 26938); depth of body 3.0-3.4 times in SL; head length 2.8-3.0 times in SL; angular preopercle, enlarged serrae on prominent lobe at the angle and a distinct notch above the serrate lobe; greatly enlarged posterior nostrils in adults (Ref. 89707).

Biologie     Verklarende woordenlijst (b.v. epibenthic)

Found mainly on rocky or coral bottoms from the shoreline to at least 55 m depth; small and middle-sized individuals commonly occur in mangrove-lined lagoons. Feeds on fishes. Sex-reversal observed (Ref. 5521). More common in island waters than along the coast (Ref. 26938). The tricolored pattern of the juveniles mimics that of the juveniles of the clown wrasse, Halichoeres maculipinna. The aggressive mimic’s behavior includes folding down the median and caudal fins, which adds to its wrasse imitation and allows it to approach its otherwise wary prey (Ref. 43465). Marketed fresh; flesh is of good quality.
