Sonoran Desert Toad

Incilius alvarius Sonoran Desert Toad - Incilius alvarius

Description: A particularly large toad, the Sonoran Desert Toad is also particularly poisonous. The poison producing parotid glands are located on the posterior end of the head, directly behind the ear. Sonoran Desert Toads also have glands on their fore and hind limbs resembling parotid glands, although those are only decoys.

Range: Southwestern United States

Habitat: Primarily found in deserts, although they also have been known to inhabit lowlands, arid grasslands, mountainous canyons, and forested riparian zones.

Wild: Insects and other invertebrates, as well as smaller amphibians, reptiles, and rodents
Zoo: Crickets and mice

Reproduction: Males normally employ one of two types of mating behaviors. They will either actively search out a mate, or will remain in a shallow pond and call, in the hopes that she will come to him. Females lay approximately 7,500-8,000 eggs in a long, gelatinous tube. The larval stage last only a month.

Fun Fact: In nature, a common lifespan lasts 4-5 years, although one Sonoran Desert Toad in captivity reportedly lived almost 15 ½ years.
