Half a giraffe’s leg is actually its foot

The legs of a giraffe are two metres (6.6 feet) long but almost half of this is actually the foot. The joint that functions as a knee is anatomically equivalent to a wrist or ankle. The giraffe balances on the tips of its toenails, but to support its weight these toenail hoofs are 30 centimetres (12 inches) across. Having such long limbs mean giraffes can gallop at 60 kilometres (37 miles) per hour for short periods.
