From Wikipedia: The giraffe is the tallest of all land animals. It can reach a height of 5.5 metres and weigh up to 1360 kg. Its closest relative is the Okapi. Its tough prehensile tongue and long neck enables it to feed on tree foliage - mainly Mimosa and the thorns of Acacia. Adult giraffe are too large to fall prey to most predators but the young are often victims and have a high mortality rate.
