National Geographic (Flying Snake)

The image of airborne snakes may seem like the stuff of nightmares (or a certain Hollywood movie), but in the jungles of South and Southeast Asia it is reality.
Flying snake is a misnomer, since, barring a strong updraft, these animals can’t actually gain altitude. They’re gliders, using the speed of free fall and contortions of their bodies to catch the air and generate lift.

Once thought to be more parachuters than gliders, recent scientific studies have revealed intricate details about how these limbless, tube-shaped creatures turn plummeting into piloting. To prepare for take-off, a flying snake will slither to the end of a branch, and dangle in a J shape. It propels itself from the branch with the lower half of its body, forms quickly into an S, and flattens to about twice its normal width, giving its normally round body a concave C shape, which can trap air. By undulating back and forth, the snake can actually make turns. Flying snakes are technically better gliders than their more popular mammalian equivalents, the flying squirrels.
There are five recognized species of flying snake, found from western India to the Indonesian archipelago. Knowledge of their behavior in the wild is limited, but they are thought to be highly arboreal, rarely descending from the canopy. The smallest species reach about 2 feet (61 centimeters) in length and the largest grow to 4 feet (1.2 meters).
Their diets are variable depending on their range, but they are known to eat rodents, lizards, frogs, birds, and bats. They are mildly venomous snakes, but their tiny, fixed rear fangs make them harmless to humans.
Scientists don’t know how often or exactly why flying snakes fly, but it’s likely they use their aerobatics to escape predators, to move from tree to tree without having to descend to the forest floor, and possibly even to hunt prey.
One species, the twin-barred tree snake, is thought to be rare in its range, but flying snakes are otherwise quite abundant and have no special conservation status.

National Geographic (Uakaris)

Uakaris are small South American primates with striking bald heads and bright red faces. (They may be attractive to mates because malarial or sick animals develop pale faces.) They have a long, shaggy coat that varies from reddish brown to orange. These monkeys live only in the Amazon River basin, preferring permanently or seasonally flooded rain forests and locations near water sources, such as small rivers and lakes.

Unlike most monkeys, uakaris have very short tails, but move nimbly in the trees without them by using their arms and legs.
These New World monkeys live in groups called troops and are quite social animals. Such gatherings may include close to a hundred animals, but uakaris split up during the day to forage in smaller groups of one to ten individuals. At night they sleep aloft, high in the rain forest canopy.
Uakaris forage during the day. They eat a fruit-heavy diet, but also consume leaves and some insects. Their powerful jaws can open a hardy Brazil nut. Most food is gathered in the trees, though during dry periods when food is scarce, uakaris will go to the ground in search of fallen seeds or roots.
Females give birth to just a single infant every two years. Reproductive ages are three (females) and six (males), so populations cannot experience rapid growth.
Unfortunately, these intelligent primates are on the verge of extinction. They are hunted in their Amazon forest homes for food and sometimes captured by indigenous peoples. They are also threatened by the destruction of their environment, as the timber industry clears ever increasing swaths of Amazon forest.

National geographic (Aardvarck)

Aardvarks live throughout Africa, south of the Sahara. Their name comes from South Africa's Afrikaans language and means "earth pig." A glimpse of the aardvark's body and long snout brings the pig to mind. On closer inspection, the aardvark appears to include other animal features as well. It boasts rabbitlike ears and a kangaroo tail—yet the aardvark is related to none of these animals.
Aardvarks are nocturnal. They spend the hot African afternoon holed up in cool underground burrows dug with their powerful feet and claws that resemble small spades. After sunset, aardvarks put those claws to good use in acquiring their favorite food—termites.

While foraging in grasslands and forests aardvarks, also called "antbears," may travel several miles a night in search of large, earthen termite mounds. A hungry aardvark digs through the hard shell of a promising mound with its front claws and uses its long, sticky, wormlike tongue to feast on the insects within. It can close its nostrils to keep dust and insects from invading its snout, and its thick skin protects it from bites. It uses a similar technique to raid underground ant nests.
Female aardvarks typically give birth to one newborn each year. The young remain with their mother for about six months before moving out and digging their own burrows, which can be extensive dwellings with many different openings.
