Diagnostic characters: body very slender, cylindrical and somewhat S-shaped; head distinctly angled to body axis at birth; anus below dorsal fin origin; numerous large, leaf-like skin flaps on body; no caudal fin; body lightly pigmented, with narrow dark bands encircling tail and dorsal third of thorax. Sequence of fin development: all fin elements (caudal fin absent) formed by birth. Head small, snout much shorter than in adults. Gut moderate. Body rings and ridges initially indistinct, but distinguishable by the short body spines. Dermal appendages become more palmate with growth.
