Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 9; Mjukstrålar i ryggfenan (totalt) : 10; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 9. This species is distinguished by the following features: 5-7 (usually 6) median predorsal scales; 3 scale rows on cheek 1(5-7), 2(5-7), 3(1-4); pectoral-fin rays 13-15 (usually 14); conical teeth on side of dental plate, none in female and usually 2 on upper and 0-1 on lower of dental plates for terminal male; lips nearly covering dental plates; caudal fin slightly rounded to truncate in female and emarginate in terminal male. Colour of patch covering cheek and gill cover of male orange, wavy band/lines on snout and cheek, pectoral fins pale green; female grey or grey-brown with 2 pale stripes on belly (Ref. 9793, 90102).

Biologi     Ordlista (t.ex. epibenthic)

Found in silty coastal and offshore areas to 20 m deep (Ref. 90102). Inhabits rocky and coral reefs from tidal pools to at least 10 m deep. Form schools with 30 to 40 individuals. Grazes on benthic algae and corals (Ref. 2935). Reproductively active terminal males become bicolored (Ref. 37816).
