Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 6 - 7; Dorsal soft rays (total): 7 - 8; Anal spines: 1; Anal soft rays: 7 - 8; Vertebrae: 26. This species is characterized by the following: small, slender with D1 VI, D2 and A I, 8; pectoral rays all unbranched, often with 14 rays, none are thickened; 22-24 longitudinal scales; 6-7 TRB; ctenoid scales on body, extending forward to just above pectoral base, but not onto head; small, fused pelvic fins forming a narrow cup, usually with a very narrow anteriorly-facing fold on fraenum, no or almost no fleshy development on pelvic spines; reduced sensory papillae on head; oculoscapular canals on head separate, with 2 anterior and 2 posterior interorbital pores, posterior oculoscapular and nasal pores absent, preopercular pores 3; no canine teeth; protrusible upper jaw, opening downward; translucent body with 6 red internal bars and small black spots on base of caudal fin (Ref. 76968).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Apparently inhabits over open sand or up in the water column. Collected using rotenone over Halimeda or Caulerpa or Zostera beds (Ref. 76968).
