Hold it there, is this a giraffe or a vampire?

This giraffe was caught by amateur photographer Bronwyn Burger in the Vaalwater Nature Reserve in Limpopo, South Africa, recently chewing on a bone that makes it look like a vampire. Giraffe are the tallest herbivores in the world and feed of a variety of plant species. They are not carnivorous! However, when nutrients are lacking in their normal daily diets, and they become nutritionally stressed, they will eat bone to get phosphorous and calcium their bodies require. Bones are manipulated in and out the mouth by the tongue while being sucked and chewed.
