Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 8 - 10; Anal spines: 1; Anal soft rays: 7 - 8. Second dorsal usually with 1 spine and 9 soft rays; first dorsal spine filamentous, reaching near end of second dorsal fin. Pectoral fin 17-19 (rarely 17). Pelvic fin with complete basal membrane and a fraenum, forming a typical gobiid cup-shaped disc. Anterior nasal tube short, 5.7- 7% HL; distal quarter of tube black. Pores present: a posterior nasal, an anterior and a posterior interorbital, a postocular, an infraorbital and 2 preoperculars. Midline of belly naked (Ref. 39927).
Known from dredge and trawl samples, from areas with encrusting invertebrates (e.g. sponges) (Ref. 39927).
