Axanthism in Green Frogs (<i>Lithobates clamitans</i>) and an American Bullfrog (<i>Lithobates catesbeianus</i>) in Maine

We document eight cases of axanthism in Green Frogs (Lithobates clamitans) and one case in an American Bullfrog (Lithobates catesbeianus) in Maine. Although this mutation has been previously reported for both species, this is the first confirmed documentation of “blue” L. clamitans and L. catesbeianus from Maine.
