About the Northern Death Adder

The northern death adder (Acanthophis praelongus) is a species of venomous snake in the family Elapidae.

The northern death adder lives in Australia and Papua New Guinea. It hunts birds, amphibians, and small mammals both by day and night. Though it resembles a viper, it belongs to the elapid family, which also includes cobras and mambas.

An envenoming by this snake is very dangerous, and all bites should be treated as medical emergencies. Main effects include local pain and flaccid paralysis, death can be caused by respiratory failure. In the case of systemic effects of envenoming key treatment is based on antivenom applications ('Polyvalent Snake Antivenom (Australia - New Guinea)' CSL Limited, 'Death Adder Antivenom', CSL Limited).
