Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 1; Radios blandos dorsales (total) : 27 - 28; Espinas anales: 0; Radios blandos anales: 26; Vértebra: 19. Maximum known size small (3.6 cm SL); soft Doral rays 27-28; anal rays 26; pectoral rays 11/11; dorsal profile of snout straight in male, slightly concave in female, without prominent hump just before nostrils; soft dorsal and anal fins not elevated anteriorly, outer margins convex; soft dorsal fin of male with second ray elongate and filamentous; caudal fin moderately long (about equal to head length), posterior margin convex; pelvis capable of moving vertically through an arc of about 40 degrees, producing a moderately large ventral flap; lobe on rear of pelvis small, directed dorsoposteriorly; pelvic fin rudiment relatively short and small, posterior segment movably articulated with pelvis; midbody scales each with up to six minute spinules located on a transverse ridge, those on caudal peduncle of male slightly longer, recurved, forming a poorly defined patch of bristles (Ref. 48594).
Inhabits sandy bottoms, possibly in areas with scattered coral clumps (Ref. 48594).
