Family: Bufonidae, Toads view all from this family

Description Oval parotoid glands. Olive to greenish-yellow. Females have dark blotches.

Dimensions 4.5-7.7cm. (1 3/4-3")

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 Musical trill, frequent intervals.

Breeding May-July. Eggs laid in shallow water.

Habitat Damp meadows on elevation of 6,400-11,000'.

Range Yosemite National Park, California.

Discussion Only found with others during breeding. Burrows underground to escape cold.
