Giraffes have the longest necks in the world. Their necks are 7 ft long, they are the tallest animal in the world. The new born giraffe is taller than 6 ft.The new born giraffe is bigger than a new born human baby and can walk for 15 minutes and a new born human baby can't even walk he can only crawl.  The baby giraffe stays with its mother for one year then it goes on its own. It takes four years to grow into a full adult. It can grow 18 feet tall. It has seven neck bones in it's neck just like your neck only that they are much longer. It takes some effort to pump the blood up its long neck so its heart is huge and it has special blood vessels to help the blood not to fall back down.
