The tallest animal in the world is the giraffe, which can reach heights of up to 18 feet or 5.5 meters. They have extremely long necks, which can measure up to 6 feet or 1.8 meters in length, and long legs that help them reach high branches for food. Giraffes have distinctive spot patterns on their fur, and they are found in various countries in Africa, such as Tanzania, Kenya, and South Africa. They are herbivorous animals and spend most of their time grazing on leaves and twigs from trees.
