wels catfish
The wels catfish ( or ; ''Silurus glanis''), also called sheatfish, is a large catfish native to wide areas of central, southern, and eastern Europe, in the basins of the Baltic, Black, and Caspian Seas. It has been introduced to Western Europe and is now found from the United Kingdom all the way east to Kazakhstan and south to Greece and Turkey. It is a scaleless freshwater fish recognizable by its broad, flat head and wide mouth. Wels catfish can live for at least fifty years and have very good hearing.
The wels catfish lives on annelid worms, gastropods, insects, crustaceans, and fish including other catfishes; the larger ones also eat frogs, mice, rats, and aquatic birds such as ducks. Recently, individuals of this species in environments that are not their native habitats have been observed lunging out of the water to grab pigeons on land.
==Habitat==
The wels catfish lives in large, warm lakes and deep, slow-flowing rivers. It prefers to remain in sheltered locations such as holes in the riverbed, sunken trees, etc. It consumes its food in the open water or in the deep, where it can be recognized by its large mouth. Wels catfish are kept in fish ponds as food fish.
