Alpine Bullhead

The Alpine Bullhead, or Siberian Bullhead, is a species of freshwater fish. It has a wide distribution, and can be found all over Asia and Europe. In northern and central Europe, it tends to prefer coldwater streams and lakes in mountainous regions. The alpine bullhead feeds on insects, crustaceans and small invertebrate prey that it finds on the stream bed. It is generally nocturnal but becomes diurnal in the Arctic during the winter. In spring, when the water temperature rises, a male will prepare a nest under a large stone and several females will lay their eggs in it. The male then guards the nest for the month or so until the eggs hatch.
