A small and moderately elongate ophidiiform fish with long anal and dorsal fins. The body and fins are uniformly pig-mented, appearing yellow to olive-brown. Adults can attain about 3.9 in (10 cm) in length. The caudal fin is distinct and separate, not confluent with the dorsal- and anal-fin bases. The pelvic fins are positioned at the isthmus, anterior to the pectoral-fin bases. Each pelvic fin has one fleshy ray that is longer than the length of the head. The eye is small and the mouth large, with the upper jaw extending well posterior to the eye. The body is covered with small overlapping scales that do not appear on the cheeks (opercular bones).
