It is a robust and rather elongate with a long and produced snout. The nostrils are reduced to a single small opening on each side of the snout. The skin is tough and scaleless. The fins are spineless and include a single posterior dorsal fin with 8-10 rays, an anal fin with 8-10 rays, pectoral fins with 15-18 rays each and a slightly rounded caudal fin.
