Description
The bighead goby is a Ponto-Caspian goby of the family Gobiidae reaching about 22 cm. Characteristic is the broad, large head; the brown-mottled body bears dark saddle blotches. Like other gobies the pelvic fins are fused into a sucking disc. The species is native to the brackish and fresh water of the Black Sea and Danube drainages, on vegetated and stony bottoms. As a bottom-dweller it hunts small crustaceans, molluscs, insect larvae and small fish. The bighead goby, like several related Ponto-Caspian gobies, spreads quickly northward across Europe via connected rivers, canals and shipping, becoming a conspicuous newcomer in places. In spring the male guards the eggs laid under a stone.
