Capybaras are the largest rodent in the world and can weigh in excess of 100 pounds! They are native to South America and inhabit savannas and dense forests near bodies of water. They are highly social animals that can be found in groups of around a hundred individuals. They are selective herbivore and are related to guinea pigs.
Bats: The Only True-Flying Mammal
Bats, the only mammal capable of true flight, are not blind - their eyes are just fine, thank you very much. But instead of eyes, most bats rely on an incredibly fine-tuned sense of hearing when they fly and hunt. Using a technique called echolocation, they emit high-pitched calls (usually above the range of human hearing), using the echos that are reflected back to them as a means of navigation and locating objects. The ears, auditory cortex, and (in a few cases) even noses of some bats are extraordinarily specialized for echolocation; there are even bats that have adapted the frequency of their calls to frequencies above or below what their favorite prey can hear!
