Family: Bufonidae, Toads view all from this family

Description Small, flat. Patterned black with greenish-yellow spots. Absent cranial crests. Dusky throat on male.

Dimensions 3.8-5.7cm. (1 1/2-2 1/4")

Warning Toads have enlarged glands (called the paratoid glands) on the side of the neck, one behind each eye. These glands secrete a viscous white poison that gets smeared in the mouth of any would-be predator, inflaming the mouth and throat and causing nausea, irregular heart beat, and, in extreme cases, death. Toads pose a danger to pets, which may pounce on and bite them. Humans should take care to wash their hands after handling a toad, and to avoid touching the mouth or eyes until having done so.

Voice Buzzing sound.

Breeding July after heavy rainfall.

Habitat Temperate shrubland, intermittent rivers, intermittent freshwater marshes, temperate desert, pastureland, water storage areas, ponds, and irrigated land.

Range Arizona & Mexico.

Discussion Only in groups at breeding ponds. Nocturnal. Mostly only males found.
