Giraffes are the tallest mammals on earth. They spend all their lives standing up - even when they sleep and have babies.
What really makes a giraffe special is its neck. Even though a giraffe's neck is very very long, it has the same number of bones in its neck as you have.
Almost all mammals, including humans and giraffes, have seven neck bones. The bones are just a little longer in some mammals than others.
Giraffes' long necks give them a good view and let them eat leaves other animals can't reach.
But their long necks are a problem when they drink. A giraffe has to spread its front legs apart so its head can reach the ground to drink water. Lucky for the giraffes that they can go many days without drinking.
