Oreoglanis

Oreoglanis is a genus of fish in the family Sisoridae native to Asia. These fish live in fast-flowing streams in China, mainland Southeast Asia and the Indian subcontinent. They are mainly distributed in the Mekong, upper Salween and Irrawaddy River drainages. They range from the Brahmaputra basin to the Lam River drainage in central Vietnam. They are easily distinguished from other catfishes by their strongly depressed head and body and greatly enlarged paired fins that have been modified to form an adhesive apparatus. The flattened shape of these fish and the large pectoral and pelvic fins provide essential adhesion in the fast-flowing waters they live in.
