Rhinos have 24-34 teeth, mostly premolars and molars for grinding and the canines and incisors are for attacking purpose. Their lower incisors can be as long as 60-70cm, weighing 2-3 kilograms, while their canines can be as long as 75 cm, even longer than a human arm. Their big mouths and amazing bite force have allowed them to pull apart and eat a watermelon with ease.
