Etymology: Eugnathogobius: Greek, eu = good + Greek, gnathos = jaw + Latin, gobius = gudgeon (Ref. 45335); indicus: From the latin indicus, referring to India; in this case the Indian Ocean, where this species occurs (Ref. 80545). More on author: Larson.
Environment: milieu / climate zone / depth range / distribution range
Marine; freshwater; brackish; benthopelagic. Tropical
Indian Ocean: Mozambique, Kenya and Aldabra Atoll in the Seychelles (Ref. 80545).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 2.7 cm SL male/unsexed; (Ref. 80545)
Morphology | Morphometrics
soft rays: 6 - 8;
Vertebrae: 26. Small, slender-bodied Eugnathogobius; first dorsal fin VI; second dorsal rays I, 7-8, modally I,7; anal rays I, 6-8, modally I, 7; pectoral rays 15-17, modally 16; longitudinal scales 32-41; TRB 10-13; headpores absent; predorsal scales 14-20; scales on body small, mostly ctenoid; gill opening restricted to just under opercle; colour pale yellowish with dark scale margins in network pattern and variably distinct dark stripe along mid-side of body (Ref. 80545).
The species appears to be marine to estuarine in habitats. The specimens from the freshwater well on Aldabra are intriguing in their isolation (Ref. 80545).
