Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 7; Raggi dorsali molli (totale) : 12 - 13; Spine anali: 1; Raggi anali molli: 11 - 12; Vertebre: 27. This species is characterized by the following: second dorsal-fin rays I, 12-13 (usually I, 12); A I, 11-12 (usually I, 11); vertebrae 10 + 17; indented tongue; posterior naris with well-developed flap on anterior rim; upper sides of the body with 12 large, closely spaced spots, these usually do not extend to dorsal edge of body; predorsal area broadly scaled to about vertical through posterior edge of preopercle (Ref. 59014).
Body shape (shape guide): elongated.
A benthic, inshore species found in coral reefs (Ref. 75154). Also found in sand patches among reefs and rubble, often in surge areas (Ref 90102).
