Diet
The Colorado River toad eats a wide variety of animals including spiders, insects, toads, snails, beetles, grasshoppers, mice, and small lizards.
Life Cycle
Just before spring rains hit the desert, Colorado River toads gather at breeding pools and streams. Mating occurs from May to July. The female lays strands of black eggs. There can be as many as 8,000 eggs in a strand. The tadpoles hatch within 2-12 days. After breeding season is over, the Colorado River toad returns to its burrow, where it spends the winter.
Behavior
The Colorado River toad is nocturnal and stays underground during the heat of the day. When a Colorado River toad is threatened, it secretes a milky-white hallucinogenic toxin from the
parotoid glands under its jaw. If the toxin gets in the mouth of predators, it can cause nausea and even death.
