Unlike most other semiaquatic animals, hippos have very little hair. The skin is 6 cm (2 in) thick, providing it great protection against conspecifics and predators. By contrast, its subcutaneous fat layer is thin. The animals’ upper parts are purplish-grey to blue-black, while the under parts and areas around the eyes and ears can be brownish-pink. Their skin secretes a natural sunscreen substance which is red-colored. The secretion is sometimes referred to as “blood sweat”, but is neither blood nor sweat. This secretion is initially colorless and turns red-orange within minutes, eventually becoming brown.
