Cheetahs are not strong predators, but they are fast. They rely on their speed—up to 70 miles per hour—to catch their prey. Everything about the cheetah is built for speed, from their non-retractable claws that act like cleats for traction, to their long tail that works like a rudder to help them change directions quickly.
Cheetahs are also known for their spotted coat. The dots are both small and large, and the pattern of spots is unique to each cheetah. The fur of cheetah cubs is darker than that of adults.
As fast as cheetahs are, they can’t outrun the threats that they face. Like a lot of animals, cheetahs are losing their habitat, as are the prey animals they need to survive. Cheetahs are also often viewed as pests by ranchers. Ranchers may shoot cheetahs to keep them away from their livestock.
Cheetahs cannot roar, but they do chirp, as well as growl, hiss, and purr.
Cheetah cubs have a silvery mane on their neck and shoulders that disappears as they get older.
Aardvarks
The aardvark gets its name from a South African word meaning “earth pig.” Although the aardvark looks like a pig, especially with its body and snout, aardvarks actually share common ancestors with elephants and golden moles. Aardvarks live throughout much of sub-Saharan Africa.
Aardvarks use their large front claws to dig holes at a rate of 2 feet (0.6 meters) in 15 seconds so they can quickly get to their favorite meal: termites and ants. Aardvarks have long, sticky tongues, which can be up to 12 inches (30 centimeters) long. Each night, they are able to dig up termite mounds and ant nests and slurp up and swallow tens of thousands of insects.
Aardvarks are most active at night and tend to live alone. During the day, they sleep curled up in a ball in their burrows. As night falls, aardvarks will emerge cautiously from their dens, jumping around on the lookout for predators. They are able to see at night, but otherwise have poor vision and are color-blind. They rely on their senses of sound and smell, using their long ears and snouts to get around and find insects.
African elephants
An adult African elephant's trunk is about seven feet (two meters) long! It's actually an elongated nose and upper lip. Like most noses, trunks are for smelling.When an elephant drinks, it sucks as much as 2 gallons (7.5 liters) of water into its trunk at a time. Then it curls its trunk under, sticks the tip of its trunk into its mouth, and blows. Out comes the water, right down the elephant's throat.
Since African elephants live where the sun is usually blazing hot, they use their trunks to help them keep cool. First they squirt a trunkful of cool water over their bodies. Then they often follow that with a sprinkling of dust to create a protective layer of dirt on their skin. Elephants pick up and spray dust the same way they do water—with their trunks.
Elephants also use their trunks as snorkels when they wade in deep water. An elephant's trunk is controlled by many muscles. Two fingerlike parts on the tip of the trunk allow the elephant to perform delicate maneuvers such as picking a berry from the ground or plucking a single leaf off a tree. Elephants can also use its trunk to grasp an entire tree branch and pull it down to its mouth and to yank up clumps of grasses and shove the greenery into their mouths.
Bison
Bison are the iconic image of the Great Plains and the Old West. They are massive, shaggy beasts and the heaviest land animals in North America.Despite their hefty size, bison are quick on their feet. When the need arises they can run at speeds up to 40 miles (65 kilometers) an hour. Their curved, sharp horns can grow to be 2 feet (61 centimeters) long.
Females (cows) and adult males (bulls) generally live in small, separate bands and come together in very large herds during the summer breeding season. Males wage battles for mating rights, but such contests rarely turn dangerous. Females give birth to one calf after a nine-month pregnancy.
Amur Leopard
Slowly stalking down the snowy hillside, the Amur leopard watches its prey through the trees. In the clearing below, a sika deer munches on tree bark, one of its few remaining food sources during the cold Russian winter. The leopard crouches, its body so low to the ground that its belly fur brushes the snow. Suddenly it bounds and springs forward, tackling the deer from 10 feet away. It’s dinnertime.Most people think of leopards prowling the savannas of Africa, but these spotted predators thrive in many different countries and habitats. Amur leopards can be found in the mountainous forests of eastern Russia and northern China. Named after the Amur River, a body of water that runs along the border of both countries, these cats are well adapted to this harsh environment. Their soft, dense fur keeps them warm in the bitter cold, and their large paws work like snowshoes to let them walk on snow without sinking.
