Giraffes live in parts of Africa，too．They are brown and yellow．Their patterns are different．Giraffes are the tallest animals of all．They are one of the world's heaviest animals，and their heats are the biggest of any animal s．They have long legs and long necks．Their necks are long，so they can reach high into tees to cat the leaves，which give giraffes most of the water they need．Giraffe's long legs mean they take big steps when they walk or run．They can run very fast， so they can protect themselves from dangerous animals such as lions．
