Yoandri Hernandez Garrido, 37, proudly displays his 12 fingers in Baracoa, Guantanamo province, Cuba. His condition, known as polydactyly, is relatively common, but it's rare for extra digits to be so perfect.

Polydactyly or polydactylism (from Ancient Greek πολύς (polus) "many" + δάκτυλος (daktulos) "finger"), also known as hyperdactyly, is a congenital physical anomaly in humans, dogs, and cats having supernumerary fingers or toes. Polydactyly is the opposite of oligodactyly (fewer fingers or toes).
