The tallest animal on Earth is a giraffe. An adult giraffe can reach a height of up to 5.5-6 meters, and most of this height is occupied by its legs and neck. The neck of a giraffe can be up to 2 meters long and consists of 7 cervical vertebrae that allow the giraffe to reach the leaves on the trees on which it feeds. Giraffes live in Africa and are one of the most recognizable animals due to their unusual appearance.
