The Giraffe (Giraffa camelopardalis) is the world’s tallest mammal and its largest species of antelope, with males taller (and usually darker) than females. Full-grown Giraffes stand up to 5.7 metres (18.7 feet) tall, and large males weigh up to about 830 kg (1,800 lb.).

Both sexes have horn-like structures on their heads that help temperature regulation and are used by males for fighting. Their extremely long necks are between 2-2.4 metres (6.6 to 7.9 feet) long and permit giraffes to browse foliage out of the reach of other animals. These three young males were standing on the road in Kruger Park South Africa doing low-intensity ‘necking’ – testing the dominance of the other male by play-fighting.
