Gummy sharks are normally grey above and silvery-white below. The species grows to a length of 1.75 m.
Gummy sharks are normally grey above and silvery-white below. The common name results from the teeth, which are arranged in a pavement-like pattern.
This species has also been called 'Sweet William'. Whitley (1940) stated that "The name "Sweet William", sometimes applied to the Gummy Shark, has been borrowed from a sobriquet for an English shark, the Tope, of which Pennant wrote, many years ago:- "It's skin and flesh has an offensive rank smell; therefore we suppose Mr Dale gave it ironically the title of Sweet William".
In Australia the species occurs in temperate waters from northern New South Wales to south-western Western Australia.
