Polydactyly or polydactylism (from Greek πολύς (polys) ‘many’, and δάκτυλος (daktylos) ‘finger’), also known as hyperdactyly, is an anomaly in humans and animals resulting in supernumerary fingers and/or toes.

    Must suck too have that defect in your wings as a bat. No flying now.

        I just assume the shape would preclude it. I can’t find any records of bats having that defect in their wings and it’s supposedly much rarer than humans to have it in their feet.
