This species of canid is also known as the timber wolf or western wolf. They are native to wild and remote areas of North America, Eurasia, and northern, eastern, and western Africa. They are the largest member of the canidae family and specialized for taking down large prey. Gray wolves are highly social animals, with complex hierarchical pack structure. Despite the fear of wolves that pervades many human societies, attacks on humans are very rare and most wolves have an instinctive fear of humans.

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!
