Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 12; Raggi dorsali molli (totale) : 15; Spine anali: 2; Raggi anali molli: 12 - 14; Vertebre: 26. Body dark reddish brown with edges of scales narrowly darker brown; black spot in axil and upper half of pectoral fin base. Body depth, 2-2.3 in SL. Preorbital width above end of maxilla 1/2 or more orbit diameter; margin of suborbital and posterior margin of preopercle strongly serrated. Suborbital scaled; scales on snout extending slightly anterior to nostrils. Tubed lateral line scales 19-20 (Ref. 39287).
Body shape (shape guide): short and / or deep; Cross section: compressed.
A shallow water species; on hard substratum (Ref. 39287). Adults are collected usually from bays and many from tide pools (Ref. 54980). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
