Giraffes like this Angolan giraffe at Jardim Zoológico are the world's tallest mammals, thanks to their towering legs and long necks. Typically, these beautiful animals roam the open grasslands across Africa in small groups of about half a dozen. Using their height to their advantage, these ungulates browse on leaves and buds in treetops that few other animals can reach, relying on their 21-inch long tongue to help successfully secure each meal. #WorldGiraffeDay #giraffe #mammal #animal #wildlif

When giraffes fight, slamming their heads and necks against each other, the impact can be heard from a hundred meters away. | National Geographic
