Lowland Copperhead
Austrelaps superbus
On a chilly morning beside a Tasmanian swamp, a lowland copperhead basks on a tussock, its coppery flanks glowing in the weak sun.
Overview
The lowland copperhead, Austrelaps superbus, is a Least Concern venomous snake of swamps, creeks, and grassland across southeastern Australia and Tasmania. Its cold tolerance, shy nature, and live-bearing habit make it one of the hardiest of Australia’s snakes, with a name that has nothing to do with the American copperhead.
A snake that tolerates the cold
By staying active at lower temperatures than most Australian snakes, the lowland copperhead can live in the cooler south, including Tasmania and the high country.
Status
Least Concern, widespread but reduced where wetlands have been drained.
