The Alpine bullhead (Cottus poecilopus) is a freshwater fish of the family Cottidae that grows up to 13 cm.
Description
The Alpine bullhead is a small freshwater bottom fish of the family Cottidae reaching about 13 cm. The scaleless, brownish mottled body has a large, broad, flattened head; it closely resembles the European bullhead but can be told apart by the longer, conspicuously banded pelvic fins. The species lives in cool, fast-flowing streams and rivers with a stony or gravelly bottom in central, northern and eastern Europe through to Siberia, often at higher altitude than the European bullhead. By day it shelters under stones; at night it hunts insect larvae, small crustaceans and fish eggs. In spring the male guards the eggs laid under a stone. It is regarded as an indicator of clean, cold water.
