A stout, venomous lizard up to about 56 cm of the south-western United States and Sonora, in succulent desert, scrub and rocky canyons. It spends nine tenths of its life in burrows or under rocks and sleeps from October to early March. Its venom serves for defence; the bite is dangerous but rarely kills a healthy adult (one confirmed death since 1930, in 2024). It was the first venomous animal given legal protection, in 1952.
