Sonoran Desert Toad (Bufo alvarius)

The Sonoran Desert toad, previously known as the Colorado River toad, is one of the largest toads native to North America. They have relatively smooth olive-green skin with huge parotoid glands behind each eye and several large warts on their hind legs. When disturbed, the parotoid glands secrete toxins as a defense. Dogs that mouth the toads can become temporarily paralyzed and sometimes die if not treated immediately.

Length: 4 - 7 ½ in. (10.1 - 19 cm)

Diet: Mostly insects, but also mice and other toads

Javelina

"Don't call ME pig!" Javelinas are able to eat spiny prickly pear pads with no obvious harm to their mouths, stomachs or intestinal tracts due to an enzyme in their saliva. Javelinas are not true pigs, they are peccaries, which are native to the Americas. True pigs are native to Europe and Asia. Wild pigs and boars are descended from true pigs brought over on boats to the new world.
