The Arroyo toad is a small toad up to 8 centimeters long that lives only in southern California. It inhabits arid areas near seasonal streams, where it breeds after rains.
The Arroyo toad differs from closely related toad species by its strong dependence on clean sandy streams with slow currents. It is important for nature as an insect consumer and as a species that indicates the state of aquatic ecosystems in California.
Quickly ejects a sticky tongue to catch prey.
Immature form that undergoes metamorphosis before adulthood.
