Both male and female have skin-covered horns, one pair on the forehead and sometimes a smaller pair farther back, on the crown. Some animals have yet another small horn, or bump, between these pairs. The tail ends in a tuft of long hairs. Gregarious animals, giraffes usually live in troops of up to 6, sometimes 12, and may occasionally gather in larger herds. A troop consists of females and their offspring, led by a male.
Males fight for possession of females, wrestling with their heads and necks.
The troop ambles around its territory, feeding mostly in the early morning and afternoon on the foliage, buds and fruits on the top of acacia and thorn trees. The giraffes may also eat grass, plants and grain crops. At midday, giraffes rest in shade and at night lie down for a couple of hours or rest standing. Births invariably occur at first light. The young is suckled for 6 to 12 months and continues to grow for 10 years.
