Giraffe

Measuring more than 5 metres, the male giraffe is the world’s tallest animal, which explains why they are almost alone when
feeding in the tree tops. Basically, the giraffe is a cow. It is a ruminant and regurgitates its food, or cud, up its two-metre-long throat for additional chewing. The walls of the giraffe’s heart are 8 cm thick, and to be able to pump the blood up to its brain, its blood pressure is three times that of a human being.
