Not only do bullfrogs eat a whole lot, but they reproduce quite a bit as well. Breeding season lasts during the summer, and males will mate multiple times. Females will mate only once, but during that single incident she can lay up to 20,000 eggs! Bullfrog tadpoles take about two years to reach maturity, and they can live nearly a decade. In northern areas the frogs will burrow into the ground during the winter, and they remain active year round in warmer climates. Male bullfrogs are very territorial and will defend their turf from other challengers, wrestling them and sometimes even holding them underwater.
