What is the heaviest rhinoceros?

The heaviest rhinoceros is the white rhinoceros, which can weigh up to 2,300 kilograms (about 5,000 pounds). There are two subspecies of white rhinos: the southern white rhino, which is the most numerous and can reach these weights, and the critically endangered northern white rhino. Their massive size, combined with a stocky build and large heads, makes them the largest of all rhinoceros species.
