About the sonoran desert toad

The Sonoran Desert toad, also called the Colorado River toad, lives in northwestern Mexico and the southwestern United States, including southern Arizona and southwestern New Mexico. It can grow to about 190 millimetres long, making it the largest toad in the United States apart from the non-native cane toad. Nocturnal and semiaquatic, it is found near streams, springs and canals and often shelters in rodent burrows. It feeds on invertebrates, lizards, small mammals and amphibians. Its skin glands produce toxic secretions, strong enough to paralyse or kill a dog, and these contain psychoactive compounds, including bufotenin and 5-MeO-DMT.

Sonoran Desert Toad facts

  • It is the only toad species with enough bufotenin to have a psychoactive effect.
  • Raccoons have learned to flip the toad over and eat its belly to avoid the poison glands.
  • It absorbs most of its water through a patch of skin on the abdomen and hind legs.
  • Its call is described as a weak, low-pitched toot lasting less than a second.

AZAThe Association of Zoos and Aquariums. Accredited members have passed an independent inspection of animal care and welfare, safety, conservation and education, repeated every five years. Many smaller facilities never apply, so “not accredited” isn't a verdict on its own. What accreditation means · How we check this
