The Oldfield Mouse is a small, pale mouse of the southeastern United States that exhibits extraordinary local color variation, with beach-dwelling populations on Florida's Gulf Coast among the palest vertebrates known. This color variation matches local soil color almost perfectly and serves as camouflage against aerial predators. Beach mouse subspecies are federally listed as threatened due to coastal development.
