Where to find me in the ZooAfrican PlainsFun Facts Although giraffes are usually silent, they can make sounds. They are able to moo, hiss and whistle. A giraffe's heart is 2' long and weights nearly 20 lbs. Giraffes are fond of acacia leaves, but the trees can fight back. They produce a sweet sap that attracts ants who build nests in the tree.
