Ectrodactyly – The Lobster Claw Syndrome

Ectrodactyly, or lobster claw syndrome, is the name given to the condition in which hands or feet have a claw-like deformation. Lord Lokhraed, guitarist and singer of French Black Metal band Nocturnal Depression, has ectrodactyly on his fretting hand, and Lee Hee-ah, a Korean pianist, has only two fingers on each hand.
Circus freak show performer Grady Stiles, also known as Lobster Boy, was the sixth generation of his family born with ectrodactyly.
