Large crescent shaped mouth, with numerous sharp pointed teeth. Flattened white belly region, with the top half of the body taking a broad expansive posture.
Colour varies from greenish brown to blackish grey, with speckled and variegated markings.
The head and body have an indistinct outline caused by the presence of numerous small flaps of skin. The gill slits are behind and lower than the base of the pectoral fins. Running along the mid-line of the head and anterior portion of the body, are a series of separate rays. Those above the pectoral fins give rise to the first dorsal fin. The reaming 3 on the head section form long spines.
