Bullhead (lat. Gobiidae) belongs to groupers and has over 2000 species living in fresh water (lakes, rivers, streams) and at sea. A bottom lifestyle of this fish is caused by physiology: a big head with large, close-set eyes allows an exceptional hunt for molluscs, worms, crustaceans, small fishes, and a special sucker on an abdomen gives the ability to cling to rocks and stay ok during storms, having fixed securely in one place.
The trunk is not more than 40 cm; the weight varies depending on the species. Bullheads do not migrate far, only in the winter live on small depth. They prefer bottom plants, grass, stones, rocks – all these are ideal places for him. Even spawning occurs in 'the nest', which is built and guarded by the male.
Catching of this fish takes place for a long time. An interesting fact is that during the great patriotic war, this fish was the main source of supply for settlements on the coast of the Azov Sea, in connection with what there is monument on the square of Berdyansk.
