Summary:
A slender brown catshark with about seven well-defined greyish saddles before the first dorsal-fin origin, and numerous large black spots and lines. The saddles are separated by pale areas and often outlined by numerous small black spots, although they may be indistinct in densely-spotted individuals.The spots extend ventrally to at least eye level, and all fins are spotted, including undersides of pectoral fins. Newly hatched pups have a simpler pattern of dark saddles.
