Capybaras have adapted to be great swimmers and live in lakes and rivers, and in grassy swampy areas. They have webbed feet so they can move on the soft muddy ground and in water. And their eyes and nose are high up on their head. Most domestic capybaras like to hang out in hot springs. They are very friendly to other animals because of their lazy lifestyle. But their natural predators, jaguars, can catch them because they are still in sight when they dip in the water.
In the future, capybaras could adapt to their natural predators by slowly gathering thick layers of strong membrane around their eyes so that they can see underwater. That way they won't have any trouble hiding from animals like jaguars.
