Description edit
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.
Distribution edit
Whip snakes of the genus Demansia are found in Australia, Papua New Guinea in the area around Port Moresby, and nearby islands.
Diet edit
Demansia whip snakes eat mainly lizards. They are diurnal (active in the day) and use their keen eyesight to hunt. Their prey dies quickly from the effects of the snake's venom.
Interaction with humans edit
In 2007 a man died after being bitten by a whip snake in Victoria. Their bites are generally regarded as akin to a bee sting and relatively harmless, but the man became woozy and went into cardiac arrest before paramedics arrived.[1]
