Colorado River toad

The Colorado River toad is a plump amphibian that lives in the dry landscapes of the southwestern U.S. and northwestern Mexico. It stands out for the potent chemicals in its skin, which can affect the nervous system of predators—and sometimes curious humans.

• Secretes toxic substances from skin glands when threatened.
• Its toxins have mind-altering effects if touched or ingested.
• Thrives in arid environments near water sources.
