Full Answer

Giraffes can grow up to 19 feet in height and weigh nearly 3,000 pounds. While the giraffe's height is advantageous for eating and searching for predators, it also poses difficulty when the animal needs to drink from a watering hole. When kneeling, a giraffe must splay its legs, making the giraffe vulnerable to predators such as lions and crocodiles. Despite this, giraffes rarely need to drink and derive most of their water from vegetation.

  • Q:

    Why do giraffes have horns?

    A:

    Giraffes have horns because they are used as weapons during inter-species conflicts. Male giraffes battle with other males for access to resources, such as food, water or mates. While both genders possess the horns, the horns of males lack the tufts of fur that female horns bear. This is because the fur and skin are worn off the male’s horns as they battle with other males.
