Capybara

• Eating their own poop: Because grass is difficult to digest, their droppings are rich in microorganisms and crude protein, so they eat their own feces for "secondary digestion and absorption." • Water masters: They can hold their breath underwater for up to 5 minutes, with their eyes, ears, and nostrils located high on their heads. Diving, escaping predators, mating, and even sleeping while floating on the water are all done in the water.
