A group of giraffes is called a tower, according to the Northern Prairie Wildlife Research Center. A tower of giraffes can most likely be seen in southern Africa.
A tower of giraffes is comprised mostly of adult females and their calves, whereas male giraffes are mostly solitary, traveling from herd to herd looking for mates. Once the bull successfully mates with the female, typical gestation is 15 months. Towers travel in small herds to fend off their chief predators: lions, alligators and hyenas. Encounters with a pride of lions can last for days. The lions track the tower through the open woodlands and across Africa's wild tundra before they isolate, chase and exhaust a helpless calf or weak female.
