More Info


Found across northern Australia from the Kimberley Region, Western Australia, to the Wenlock River in the Gulf of Carpentaria, Queensland, Australia and just west of the dividing range west of Port Douglas, Queensland. (currently not know from rivers in eastern Queensland). Also found in southern West Papua, Indonesia and Papua New Guinea. Adults inhabit freshwater rivers and streams from about 1 km above tidal influence to 400 km inland.


Dorsal fin V-VI + I, 8-10; Anal fin I, 7-8; Pectoral fin 17-21; Caudal fin (segmented rays) 15-18; Gill rakers 0-2 + 1 + 7-9; Longitudinal scale count 28-33; Predorsal scale count 18-24.
Mouth moderate; reaching to below anterior margin of eye; operculum with large patch of small mostly cycloid scales (10-20 scales) in 2 or 3 rows; pectoral base covered with small cycloid scales in adult, partly scaled to naked in specimens below 40 mm SL; no extra lateral canal pores above operculum; papilla line 6 absent; papilla lines composed of single row of papillae; body with a series of large spots on midside, each covering 2-3 scales in longitudinal direction on midside and one row above and one row below midside scales.


The species is most likely amphidromous, breeding in freshwater, with marine larval and post-larval stages, before returning to rivers. 


The species is named  munroi after Ian Munro, who collected and accumulated material of Glossogobius from Australia and New Guinea.
