Habitat: Breeding habitat: Breeding occurs in permanent bodies of water.
Summer habitat: This highly aquatic frog prefers large bodies of water such as lakes, ponds, sluggish streams, and backwaters of rivers. Although introduced local populations occur in several counties in central and southern Minnesota, this species is only native to the southeastern corner of the state.
Winter habitat: Aquatic. (MN DNR, 2022)

Reproduction: Bullfrogs begin to breed in wetlands, ponds, and shallow lakes between age four and eight. They breed later in the year than many other frogs. A female bullfrog may lay 2,000 to 25,000 eggs on the surface of the water after mating. It takes two years for bullfrog tadpoles to develop legs and emerge from the water and three additional years to reach maturity. (MN DNR, 2022)
