yellow-faced whip snake
All species of the genus Demansia are gray, brown, gray-green, or beige, save for Demansia psammophis (yellow-faced whip snake), which may be cream-coloured. Whip snakes are long and slender. They have large eyes and relatively small heads that are only slightly wider than their bodies. All species in the genus Demansia are venomous.
The effects of whip snakes' venom on humans are relatively mild compared to that of many other Elapid snakes, but they are known to have a very painful bite. Envenomation by a large individual can be dangerous, and medical attention should be sought. One known fatality has been attributed to a Whip Snake, that of Ron Siggins in 2007.
