The California Red-Legged Frog became the official state amphibian of California on January 1, 2015. This species of frog is probably most well-known for its appearance in Mark Twain's short story "The Celebrated Jumping Frog of Calaveras County". It is the largest native frog in the Western United States and it is almost exclusively located in California. See also Other State Symbols of California and the Calaveras County Fair and Jumping Frog Jubilee.
