The black-headed spider monkey is an arboreal, diurnal species of primate native to Central and South America (New World monkey). Spider monkeys tend to travel and forage in the upper levels of the forest – when travelling they spend much more time hanging and swinging by their arms (brachiation) than they do walking or running on all fours. Fruit makes up the bulk of their diet, followed by other types of vegetable matter, honey, and occasionally insects such as termites and ants.
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!
