The Northern Red-legged Frog is found along the western coast of North America. They breed from January to March depending on how far north they are located. Farther north they are, the later they breed. Egg masses from the frogs number between 300 and 5000 eggs. Eggs hatch in about a week into tadpoles. The tadpoles take 3 to 7 months to fully undergo metamorphosis. Some of the tadpoles take until the next spring to turn into frogs. Adult frogs can live up to 10 years.
