The California red-legged frog is the largest native frog in the western United States. It is
endemic to California and Baja California, Mexico. It is typically found from sea level to
elevations of approximately 1,500 meters (5,000 feet). The California red-legged frog ranges in
length from 1.5 to 5.4 inches, with females attaining a significantly longer body length than
males. Larvae range from 0.6 to 3.1 inches in length. A complete description of the frog can be
found in the final rule listing the frog (Federal Register 61: 25813-25833) and the final rule
