A Bloat of Hippopotamus
Hippos are the third-largest living land mammal, after elephants and white rhinos. Its name comes from the ancient Greek for “river horse.” Hippos rely on water or mud to keep cool — this accounts for the amount of time they spend in the water. Instead of sweating, they secrete a viscous red fluid, which protects the animal’s skin against the sun and possibly acts as healing agents.
