Desert Duets: Spadefoot Babies Web Page
Female spadefoots lay their eggs in summer desert rain pools. The eggs hatch within 36 hours. The female may lay as many as 3,000 eggs, but many die because rain puddles and pools can dry up before the eggs hatch or tadpoles develop. Some of the tadpoles are smaller vegetarians and some are larger with powerful jaw muscles. If their food supply is low, the larger tadpoles will eat the smaller ones.
