DESCRIPTION: up to 7", one of the largest native toads in North America. Upper body is uniform olive color. Has large parotoid glands behind eyes and a white tubercle (bump) behind the mouth on each side. Male's call is surprisingly weak and sounds like a low-pitched ferry whistle.
NATURAL HISTORY: Previous name was Colorado River Toad. Occurs in a variety of habitats, from desertscrub to oak-pine woodland and may be seen some distance from water (also commonly found in swimming pools). A potent toxin is released from the parotoid glands and other glands that can kill dogs (look for pawing at the mouth and excessive salivation and wash out mouth with water). As with all amphibians, always wash your hand after handling.
