The giraffe (Giraffa camelopardalis) is an African even-toed ungulate mammal, the tallest living terrestrial animal and the largest ruminant. Its specific name refers to its camel-like face and and the patches of color on its fur, which bear a vague resemblance to a leopard's spots. The giraffe is noted for its extremely long neck and legs, as well as its horn-like ossicones. It stands 5–6 m (16–20 ft) tall and has an average weight of 1,600 kg (3,500 lb) for males and 830 kg (1,800 lb) for females. It is classified under the family Giraffidae, along with its closest extant relative, the okapi. There are nine subspecies, which are distinguished by their coat patterns.
