They have small "horns" or knobs on top of their heads that grow to be about five inches long.
These knobs are used to protect the head in fights.
They can be found in central, eastern and southern Africa.
Their long necks help them eat leaves from tall trees, typically acacia trees. If they need to, they can go for several days without water. Instead of drinking, they stay hydrated by the moisture from leaves.
They defend itself against threats by kicking with great force. A single well placed kick of an adult giraffe can shatter a lion's skull or break its spine.
They have one of the shortest sleep requirements of any mammal, which is between 20 minutes and two hours in a 24 hour period.
