The Australian snake that hunts by turning its own tail into a lure

Nature · Published 3 October 2026 Swipe more like this →

In short: The common death adder is a master of patience. Instead of chasing prey, this venomous elapid hides under leaf litter for days, twitching its grub-like tail to bait unsuspecting animals. While it is not naturally aggressive, its reliance on camouflage makes it a hidden danger in Australian bushland.

First described in 1802, the common death adder (Acanthophis antarcticus) is a member of the Elapidae family, distinguishing it from the true vipers found elsewhere in the world. It is a thick-bodied snake with a distinctively broad, triangular head and a pattern of red, black, and brown bands. Reaching lengths of 70 to 100 centimetres, it inhabits diverse environments across eastern and coastal southern Australia, as well as parts of Papua.

The snake's hunting strategy is highly specialized. By burying itself beneath debris and leaves, it remains nearly invisible to passing birds, small mammals, and lizards. It may wait in a single coiled position for many days, using its tail as a lure to draw prey within striking distance. Once an animal investigates the movement, the adder strikes with high-speed precision, injecting venom and waiting for the victim to succumb before consuming it.

Reproduction in this species is also unique among many snakes, as females give birth to live young rather than laying eggs. A typical litter ranges from 3 to 20 offspring, though records exist of more than 30 in a single birth. Despite its widespread nature, the species faces significant ecological pressure. The invasion of cane toads poses a dual threat: the toads consume young adders, while adults that attempt to eat the toads are often killed by the toxins secreted from the toad's skin glands.

Because the death adder relies on staying perfectly still to avoid detection rather than fleeing, it is considered particularly dangerous to humans who inadvertently step near them. While it has disappeared from areas like Victoria, it remains a significant, if elusive, predator in the forests, grasslands, and heaths of the Australian coast.
