Main predators of adults are snakes, raptors, carnivorous/omnivorous mammals, & wading birds. Diving beetles, predaceous diving bugs, giant water bugs, many fish, crayfish, dragonfly nymphs, & many birds prey on tadpoles.

Spend 1st 2 months in water as tadpoles, then move onto land & become toadlets until sexual maturity reached at age 2.

Males make cricket-like trill in spring to attract females.

Adults more nocturnal than toadlets who sometimes come out during the day

Females can lay thousands of eggs in a season.

They can burrow up to 3 ft underground to hibernate in cold weather.

Fun Fact(s):
Some antipredator behaviors involve playing dead & puffing up their bodies.

Warty skin produces poisonous milky fluid, which is harmful if swallowed or in the eyes. Poison provides great protection from many potential predators. Tadpoles have these defensive chemicals as well.

Toads don’t cause warts.
