The wels catfish has also been observed taking advantage of large die-offs of Asian clams to feed on the dead clams at the surface of the water during the daytime. This opportunistic feeding highlights the adaptability of the wels catfish to new food sources, since the species is mainly a nocturnal bottom-feeder. [22]
Siluridae is the nominate family of catfishes in the order Siluriformes. About 105 living species of silurids are placed in 12 [1] or 14 [3] genera.. Although silurids occur across much of Europe and Asia, they are most diverse in Southeast Asia, beyond which their diversity decreases in temperate East Asia, the Indian subcontinent, Southwest Asia, and Europe.

For a fuller treatment of this taxonomy, see the vertebrate article. The position of hagfish in the phylum Chordata is not settled. Phylogenetic research in 1998 and 1999 supported the idea that the hagfish and the lampreys form a natural group, the Cyclostomata, that is a sister group of the Gnathostomata. [3] [4]

Siluriformes, or catfish, are a diverse order of fish distinguished by prominent barbels, which give the image of cat-like whiskers. In Swedish waters, the only species of this order is the wels catfish (Siluris glanis). This very large freshwater fish is common over much of continental Europe, and was once well known in Sweden.
Airbreathing catfish comprise the family Clariidae of the order Siluriformes. Sixteen genera and about 117 species of clariid fishes are described; all are freshwater species. [ 1 ] Other groups of catfish also breathe air, such as the Callichthyidae and Loricariidae .
