No, hippos do not have fur. Instead, they have a thick, nearly hairless skin that helps them stay cool and protects them from the sun.
Hippos, or hippopotamuses, have a unique skin structure that is composed of a tough outer layer. This skin can be quite thick, measuring up to two inches in some places, and it helps to prevent water loss.
While they do have some sparse hair on their bodies, especially around their ears and tails, it is not fur in the traditional sense that you might find on other mammals. Instead of fur, the skin secretes a natural sunscreen that acts as a protective barrier against the harsh sunlight and makes their skin appear somewhat slick and oily.
In summary, hippos are largely hairless with thick skin, allowing them to thrive in their aquatic habitats while minimizing the risk of sunburn and dehydration.
