5. Giraffe – The Tallest Land Animal In The World

Giraffe – The Tallest Land Animal in the World

The giraffe is known as the tallest land animal on Earth. Its height and anatomy make it an impressive creature. On average, a giraffe can reach a height of 14 to 18 feet, with males being taller than females. These incredible heights are mainly due to their long neck and legs.
