Raccoons are active-at-night, or nocturnal, mammals that live throughout much of the world, from North and South America to Asia, in wooded areas and big cities alike. During winter in cold northern climates, raccoons sleep for extended periods, although they don’t actually hibernate. To prepare for cold winters, raccoons pack on extra body fat in fall. This extra fat helps provide the raccoon with energy when it’s too cold to search for food. On land, raccoons lumber around on all four paws like a bear. Among the raccoon’s favorite foods on land are: fruits, seeds, nuts, birds‘ eggs and plants. In cities, raccoons scavenge around garbage bins and will eat scraps of food and other trash found there. Raccoons are also excellent swimmers, hunting fish, frogs, and crayfish. Raccoons live for around one to three years in the wild. In captivity, where the raccoon doesn’t need to worry about finding food or outwitting predators, some have lived as long as 20 years.

Porcupines are lumbering, rotund rodents with needle-like spikes, called quills, covering their back, sides, and tail. A single porcupine can have more than 30,000 quills, which are actually sharp bristles of fused hair. When another animal attacks the porcupine, its quills detach, burrowing into the adversary’s flesh and inflicting painful, potentially deadly wounds. It’s easy to tell when porcupines are mad: They stomp their feet, hiss, and shake their quills, which normally lie flat against the porcupine’s body. While porcupines are rarely aggressive, they’ll defend themselves by charging or swatting their spiked tail at opponents. Porcupines are herbivores, eating leaves, plants, fruit, and the tender layer of tissue beneath the bark of trees. A porcupine can fell a whole tree if it removes too much bark. The head and body of a porcupine is between 25 to 36 inches (60 to 90 centimeters). And the tail can add another 8 to 10 inches (20 to 25 centimeters) to the entire length.

A caracal crouches in the tall grass, eyeing a bird perched on a nearby shrub. Suddenly the wild cat bursts from her hiding spot and bolts toward the fowl. As the bird takes off, so does the caracal. She leaps up six feet and swats her prey with her paw, causing it to fall to the ground. Then the cat scoops up the bird in her mouth. It’s dinnertime. SOLO CAT Caracals live on rocky hills or grasslands in the Middle East, Africa, and south Asia. The animal is one of more than 30 species of small wild cats. Most caracals grow about three feet long and can weigh over 40 pounds. The feline is usually most active after sunset. And this cat likes its me-time—adults spend much of their days alone, hunting for birds, rodents, rabbits, and gazelles. HUNTING AND HUGGING The body of a caracal is built for sneak attacks. Caracals are superfast, and with footpads cushioned by stiff fur they make practically no noise as they sprint toward targets. The animals’ strong hind legs allow them to jump six feet in the air—the height of a tall adult human. Tufts of hair on the tips of a caracal’s ears may enhance their hearing, making it easier for the cat to listen for prey. These hunters have a softer side too. Mom caracals (which usually have three babies in each litter) cuddle with their young. And the babies cuddle each other too. See, even ninjas need to snuggle sometimes. Text by April Capochino Myers

Hedgehogs have prickly spines everywhere except on their face, legs, and bellies. By curling into a tight ball and tucking in their heads, tail, and legs, they protect the parts of their bodies that do not have stiff, sharp spines. Often compared to pincushions, hedgehogs depend on their spines for defense—both while they sleep and when they face enemies. The head and body of adult hedgehogs range from 5 to 12 inches (13 to 30 centimeters) long and their tail can add 1 to 2 inches (3-5 centimeters). When hedgehogs are born—up to seven in a litter—their spines are soft and short. Soon after birth, their spines harden, becoming stiffer, sharper, and longer. Babies stay in the nest until they’re about three weeks old. By that time, their eyes are open, their spines are effective, and they can safely follow their mother outside the nest as she looks for food. Top on the hedgehog’s menu are insects, followed by small mice, snails, lizards, frogs, eggs, and even snakes. Hedgehogs sometimes add extra protection to their spines by „self-anointing.“ Immune to poisons in some plants, hedgehogs sometimes eat those plants and then make a frothy saliva in their mouths. The hedgehogs then lick their spines, spreading the saliva with the plant’s poison all over the spikes. Though hedgehogs mainly stay on the ground, they swim quite well and even climb trees.

You may not have seen a skunk in your neighborhood, but you’ve probably smelled one. Their smelly spray, called musk, is not easy to ignore! Skunks live all over North and South America, in rural areas, suburbs, and the city. But if you see one, watch out! The spray, which comes from two glands near the base of the skunk’s tail, can hit a target 12 feet (3.7 meters) away. If you are lucky, you may get a warning before being sprayed. If threatened, skunks stamp their front feet, lift their tail, and growl. Some species of skunk even spring into a handstand before spraying, which puts the skunk’s warning markings on full display. If the person or animal doesn’t retreat, the skunk aims the spray at the eyes, allowing the skunk to escape. The spray can remain on its target for days. Skunks are nocturnal, which means they search for food at night and sleep in dens lined with leaves during the day. Their favorite foods include fruit and plants, plus insects, bird eggs, small rodents, and birds. Birds like the great horned owl prey on skunks. Scientists believe it’s because the birds don’t have a very good sense of smell, which makes the skunk’s spray useless in an attack.

Though hyenas look like large dogs, they are actually more similar to cats like lions and tigers. Hyenas have very powerful jaws and strong teeth. Spotted hyenas live in large groups called clans, which can include up to 80 hyenas. They hunt in smaller groups and use various techniques to attack different types of animals. They are successful hunters in groups or alone and will even try to catch fish, birds, and bugs in lakes. After catching their prey, spotted hyenas celebrate by making a sound like a laugh. This giggle tells other hyenas that they have food to share, but it can also attract other animals, such as lions, to the feast. This can spark a game of tug-of-war. The most common type is the spotted hyena. Baby spotted hyenas, called cubs, are born with black fur that grows out as lighter hair with spots. Spotted hyena clans, which are led by females, often meet at a large den in the middle of their territory. Hyenas have a complicated system of greeting and interacting with each other. Since they are in charge, females usually get first choice for the best mud baths and other favorite hyena activities.
