The tallest animal in the world is the giraffe. On average, giraffes can grow up to 18 feet tall, with their legs alone measuring up to 6 feet. The neck of a giraffe can also be up to 6 feet long, and their long legs enable them to run at speeds of up to 35 miles per hour. Giraffes are known for their unique spotted coat, which helps them blend in with their surroundings and avoid predators. They are found in various parts of Africa, mostly in savannahs, grasslands, and open woodlands.
