Also known as the Common Death Adder, this species is native to eastern and southern Australia, as well as Papua New Guinea. The species avoids desert areas but is plentiful in wooded or grassy areas. These reptiles are quite adept at blending into their surroundings, enabling them to hunt by stealth. One female Death Adder can produce three to over thirty live offspring.

Where To Find the Death Adder

Seldom found in desert areas, the Death Adder is most at home in heath, woodland, forest, and grassland areas. Because the coloring found from head to tail is a type of camouflage, it is common for people to stumble upon these snakes accidentally. As with most snake species, the adder is less likely to be active during the hottest part of the day.

Death Adders have been found in every Australian state and territory besides Tasmania, showing the species’ adaptability. Sydney is the only urban area that has been known to have a population of these snakes. People who encounter these snakes are most likely to do so while engaging in hiking or similar activities.
