Scales and lateral line absent; some sensory papillae on sides. 
A single, short-based dorsal fin close to, but distinctly separated from caudal fin; anal fin similar to and opposite dorsal fin, anterior rays of neither fin swollen at base; caudal fin rounded. Pectoral fins rounded, with no fleshy pad ventrally on bases. Pelvic fins united into a relatively large ventral sucking disc, consisting of anterior and posterior halves, posterior edge with fleshy fringe.
