Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 7 - 8; Anal spines: 1; Anal soft rays: 7 - 8; Vertebrae: 27. Distinguished by following characters: second dorsal fin with I,7-8 rays, usually I,8; pectoral fin with 15-16 rays, usually 15; 31-35 longitudinal scales; 9-12 transverse scales backward; 12-14 scales around caudal peduncle; 17-21 small predorsal scales, reaching to slightly anterior of rear preopercular margin; ctenoid scales on sides of body extending forward in wedge to behind pectoral fin; sensory papillae on head in distinct transverse pattern; side of the body with numerous short papilla rows; gill opening oblique, shoulder girdle smooth; first spine of dorsal fin longest in males, second spine longest in females, no spines elongate; and head, body and fin rays plain dark brown to blackish (Ref. 97638).
Facultative air-breathing in the genus (Ref. 126274); Observed to hide in the warm shallows, deep among coarse gravel substrate. Occurs syntopically with Mugilogobius latifrons and Glossogobius flavipinnis in shallow gravel habitats (Ref. 97638).
