Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 13 - 17; Rayons mous dorsaux (Total) : 8 - 12; Épines anales: 1; Rayons mous anaux: 16 - 21. Small supraorbital tentacle; first dorsal fin in females shorter by 50% than second dorsal fin; in males, shorter by 25%; body translucent gray in both sexes, edges of scales varying from pink to dark reddish brown, the pink-edged scales forming blotches along back; caudal fin base bearing a white bar; top of head red; female head brown and cheek with small white spots, red lower and posterior upper lip; lower part of male head black with exception of lower lip to end of maxilla being bright red and upper part of opercle red. Dorsal rays III + X-XIV + 8-12; lateral line interrupted, 15-20 + 15-21; mandibular pores 4 + 1 + 4 (Ref. 54980).
Body shape (shape guide): elongated.
Adults are found in shallow water and tidal pools (Ref. 13227). They feed on gastropods (Ref. 94105). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).
