Main predators of adults are snakes, alligators, turtles, birds, carnivorous/omnivorous mammals, larger frogs, many fish, lizards, salamanders, & giant water bugs. Diving beetles, dragonfly nymphs, damselfly nymphs, & larger amphibian larvae eat tadpoles.

They’re usually nocturnal (active at night).

Calling/breeding season lasts from late April to early August.

A female can lay 1,000-2,000 eggs a season, with each clutch containing around 40 eggs.

Tadpoles metamorphose into froglets at 2 months old, becoming adults at 2 years old.

During breeding season, males make shrill, chirp-like calls at night. Sometimes, calls made during day in response to loud noises.

Hibernate in winter by taking refuge in trees.

Fun Fact(s):
They’re often kept as pets.

Yellow in groin/leg areas helps deter predators, since it confuses them.

It produces glycerol when exposed to colder temperatures, which acts as natural antifreeze.

Their large sticky toe pads help it cling to surfaces.

They’re excellent at camouflage.
