According to WCS, "Colorado river toads are found in the northern parts of Mexico, the southern parts of Arizona and New Mexico, and the southeast corner of California. They live in a variety of desert and semi-arid habitats: brushy desert, semi-arid grasslands, and woodlands. These toads are semi-aquatic and usually found in large, somewhat permanent streams, occasionally near small springs, temporary rain pools, human-made canals, and irrigation ditches. They frequently live in rodent burrows."

Colorado river toads eat snails, insects, lizards, mice, and other smaller toad species.

The Colorado River toad is known for psychoactive compounds (5-MeO-DMT and bufotenine) present in its venom. Some people have been known to smoke dried venom for an intense high, something that is considered quite dangerous.
