Explanation

The elephant is the only mammal with four knees. This is because elephants have unique front leg anatomy - what appear to be the front 'knees' are actually wrist joints that bend backward, giving the appearance of four knee joints. Other mammals like cats, dogs, and cows only have two true knee joints on their hind legs.
