From the blue-footed booby's undeniably vibrant pedicure to the terrifying, horror villain-esque toes of an aye-aye, these animals have been stomping around with the weirdest feet on the planet. Some animal feet replicate humans' just a little too closely for comfort (we're looking at you, unsettling gorilla toes) while others are just bizarrely oversized.
Though animals' colorful array of absolutely ludicrous feet may seem random, every foot serves an important evolutionary function. Just like strange animal mouths help our furry friends chomp, weird feet help them climb, balance, and run. Sloths have giant claws that allow them to hang from trees, and flying lemurs have toes equipped with suction cups that help them navigate any surface. In any case, it's no small feat to live with such outlandish feet.
