The weight of an adult giraffe is about 1600 kilograms or 3500 pounds. Giraffes can grow to a height of 16 to 20 feet. Males are usually taller and heavier than the females.
The nine varieties of giraffes are the Reticulated, West African, Rothschild, Thornicroft, Masai, Angolan, Kordofan, Nubian and South African. Giraffes are characterized by a long neck and long front legs. The neck can grow to a length of 6 feet, and it accounts for one-third of the body weight of the giraffe. The giraffe feeds on dry grass and can reach up to devour leaves at tall heights.
