The death adder is the Australian snake named for a death-bringing bite and is among the world’s most venomous snakes.
Death adders are ambush predators. They usually remain hidden in leaf litter, sand or vegetation, relying on camouflage rather than actively pursuing prey. A distinctive tail lure can attract small animals close enough for a rapid strike. Their short, stout bodies and triangular heads make them look somewhat like vipers, although they are elapids, the same broad snake family that includes many Australian venomous species.
Several death adder species occur in Australia and nearby regions. Their venom affects the nervous system, and untreated bites can cause paralysis. Modern antivenom and emergency medical care have greatly improved outcomes, but a suspected bite remains a medical emergency.
The common name is not a claim that every bite is fatal. It reflects the historical danger of envenomation before effective treatment existed. They should never be handled, even when apparently motionless.
