From hiccups to goosebumps, we all experience different body quirks from time to time.
This person has ulnar dimelia, also known as ‘mirror hand syndrome’, which means there’s no thumb and seven or eight fingers on each hand
But for some of us, these traits are more unusual than others – and people are certainly proud of it.
This image gallery, complied by Bored Panda, reveals some of the most unique cases from around the world.
They include a baby born with naturally pointed “elf shaped” ears and a man with “mirror hand syndrome” meaning he has no thumb.
Others include someone with “tentacles” hanging from the underside of their tongue and another person who can bend their hand completely backwards.
MIRROR HANDS
