The non-native walking catfish, A group of walking catfish crosses a parking lot on a rainy day. Photo courtesy USGS. , the walking catfish, has an elongate body that is broader at the head, tapering toward the tail. It is readily recognizable as a catfish with four pairs of barbels (whiskers) and fleshy, papillated lips. The teeth are villiform (small and bristle-like), occurring in patches on the jaw and palate (Jayaram, 1981). The eyes are small. The pectoral spines are large and robust and finely serrate along the margins. There is no dorsal spine. The dorsal fin is continuous and extends along the back two-thirds of the length of the body. The dorsal, caudal, and anal fins together form a near-continuous margin; the caudal fin is rounded and not eel-like though it is occasionally fused with the other fins (Talwar and Jhingran 1991). The complete spine/ray count is: Dorsal = 62-72; Anal = 45-58; Pectoral = I + 8-11 (Sen 1985).
