The giraffe is the tallest land animal in the world, with long legs and a long neck. It lives in Africa and eats leaves.
Usually, a male (雄性) giraffe is taller and heavier than female (雌性) giraffe. When it walks, it moves both legs on one side, and then both legs on the other side. The giraffe usually sleeps for about 2 hours at night. It’s funny that it sometimes can sleep for a short time standing up.
A female giraffe can have a baby when it is 4 years old, and it usually carries the baby for about 15 months. A newborn (新生的) baby is about 1.8 metres tall. And it can live to 25 in the wild.
