Demansia psammophis, commonly known as the yellow-faced whip snake, is a species of venomous snake in the family Elapidae, a family containing many dangerous snakes.

Geographic range[edit]

D. psammophis is endemic to Australia.


D. psammophis is a long thin snake with a narrow head. Dorsally, it is greyish green to grayish blue in colour. Below the eye is a black "comma"-like marking which extends to the edge of the lip; this black marking is edged with yellow in front and behind. A white-edged dark line is seen across the snout, especially in juveniles.

Average total length (including tail) is 80 cm (31 in), maximum 1.2 m (47 in). Hatchlings are 20 cm (7.9 in) long.


D. psammophis is a lizard eating specialist, and it is common throughout its range.


Although not an aggressive species, the bite of D. psammophis is to be avoided, as extreme pain will affect the bitten limb.
