"Perfect" Polydactylism in Hind Feet of a Gray Squirrel

An adult gray squirrel from an isolated natural population had seven toes and nine plantar tubercles on each hind foot. The extra digits were articulated with supernumerary cuneiforms and appeared to have been functional. Polydactylism in wild adult rodents is probably a rare anomaly.
