 The lollipop catshark is so named because of its peculiar tadpole-like shape, with an enormously expanded head and branchial region (containing the gills) coupled with a slender, cylindrical body tapering towards the tail.The head is wide, flattened, and rounded, comprising a third of the total length in adults.The snout is very short and blunt, with widely spaced nostrils flanked by moderately developed flaps of skin.
