Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 7; Μαλακές ραχιαίες ακτίνες (συνολικά) : 13 - 14; Εδρικές άκανθες: 1; Μαλακές εδρικές ακτίνες: 6 - 8; Σπόνδυλοι: 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).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
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).
