The wels catfish is defined by a long, scaleless body; a broad, flat head; and an extremely wide mouth containing rows of small, sandpaper-like teeth — hundreds of them. It also has two sets of barbels (whisker-like organs) on the upper and lower jaw, which help the fish hunt its prey in the murky waters of large lakes and slow-flowing rivers across Europe. The wels catfish is an adept hunter, first using its pectoral fins to create a disorienting eddy and then taking advantage of its vast, vacuum-like mouth to suck prey in and swallow it whole.
