It is the smallest of three species of snake found in Tasmania and is Australia's most cold-tolerant snake, even inhabiting areas on Mount Kosciuszko above the snow line. Growing to only about 40 cm (16 in) in total length (including tail), this snake feeds almost exclusively on skinks. It belongs to the genus Drysdalia, and is often referred to as the whip snake in Tasmania (true whip snakes from Australia are from the genus Demansia and are only found on the mainland). This species gets its common name from a thin, white line bordered above by a narrow black line that runs along the upper lip. D. coronoides is viviparous.
