As their name suggests, Desert Death Adders come from arid and semi-arid climates. They are widespread through the deserts of central and Western Australia.
They are often associated with Spinifex, on sandy dunes, rocky outcrops and sometimes wooded areas, gibber deserts and coastal dunes in WA. Like other Death Adders, these snakes spend much of their time mostly buried in sand.
Death Adders are cryptic, ambush predators which attract prey to themselves rather than hunting it down. At the end of the tail is a modified section, flattened out somewhat like a flag.
This flattened section is a different colour from the body, usually black but sometimes white or yellow, with or without black markings.
