Morphology | Morphometrics
This species is distinguished from other gobies in freshwaters of Adriatic basin and western Italy by the following characters: males with small black spots on body; with cephalic lateral line canals; anterior oculoscapular canal extending to snout; branched rays in second dorsal 8-9.5; anal origin below simple of first branched ray of D2; total scales in midlateral series 36-42; completely scaled caudal peduncle (Ref. 59043).
Found in inshore habitats, lagoons, lakes and large to medium-size rivers; on sand or mud bottom. Spawns after first winter in March-July; individual females spawn several times during a season. Adhesive eggs deposited under or between stones, shells and aquatic plants and males guard the eggs until hatching. Feeds on a wide variety of benthic invertebrates (worms, amphipods, Ref.4696) (Ref.59043).
