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.

Coyotes once lived only in prairies and deserts of the western United States and in Mexico. Today they thrive almost anywhere in North America. Adaptability—that’s the main reason for the success of the coyote. A coyote is naturally adaptable because it eats such a wide range of food. If it can’t find mice or voles to eat, lizards, insects, or even garbage will do. In Native American stories coyotes are clever and tricky. Some coyotes kill calves and lambs on people’s ranches and farms. For a century people have tried to kill coyotes by using poison, traps, and guns. Still coyotes continue to thrive. This trickster of Native American tales often gets fooled—but it always bounces back. Coyotes vary in body size from 32 to 37 inches (81 to 94 centimeters). Their tails can be up to 16 inches long (41 centimeters).

Pufferfish can inflate into a ball shape to evade predators. Also known as blowfish, these clumsy swimmers fill their elastic stomachs with huge amounts of water (and sometimes air) and blow themselves up to several times their normal size. Some species also have spines on their skin to ward off predators. Even if a predator gobbles up a puffer before it inflates, it won’t enjoy the snack. Most pufferfish contain a toxic substance that makes them foul tasting and potentially deadly to other fish. The toxin is deadly to humans. There is enough poison in one pufferfish to kill 30 adult humans, and there is no known antidote. In Japan, they are called fugu and are a very expensive, delicious treat. They are prepared only by trained, licensed fugu chefs. Most puffers are found in tropical and subtropical ocean waters, but some species live in brackish and even fresh water. Some species of pufferfish are considered vulnerable due to pollution, habitat loss, and overfishing, but most populations are considered stable.

The pileated woodpecker is one of the largest woodpecker species in North America and its look is unmistakable—a large black bird with white on each side of its neck and a red crest on its head. When it flies, white flashes are visible under its wings. The sound of the pileated woodpecker’s hammering carries a long distance through the woods where they live. They drum to attract mates and to establish the boundaries of their territory—warning other males away. They use their beaks to peck and dig under bark to find carpenter ants, beetle larvae, and other insects and will often dig large, rectangular holes in trees to uncover their meals. Some holes are so big that they weaken small, young trees. The birds also strip pieces of bark from trees looking for food. Generally, however, pileated woodpeckers help keep a forest healthy by eating wood-boring insects. A nesting pair of pileated woodpeckers usually makes a nesting hole in a large, older tree. During the day, both parents take turns incubating, or sitting on, the eggs to keep them warm. At night, only the male incubates the eggs. They generally lay four eggs at a time, which take about two weeks to hatch.

Indian peafowl are a species in a group of birds called pheasants. The males are called peacocks, while the females are called peahens. Together, they are peafowl. Peafowl are among the largest of all birds that fly. (Ostriches, emus, and other such birds are bigger, but cannot fly.) The beautiful feathers that cover the tails of a peacock are 5 feet (1.5 meters) long—longer than the bird’s body—and can be displayed in a spectacular fan of brilliant colors. These long feathers actually grow from the bird’s back not the tail. He elevates them by raising the much shorter tail feathers underneath them. Peahens are more drab than their male counterparts, with mostly brown on their back with a white belly. Females don’t have long tail feathers, but they do have a crest on their head and green neck feathers. Indian peafowl are native to India and Sri Lanka, in South Asia. They’ve been introduced to other countries, usually as exhibits in parks, zoos, and nature centers or as domestic pets. The head and body of adult peafowl range from 3 to 4 feet long and their tail can be 5 feet long.

Harp seals spend most of their time diving and swimming in the icy waters of the North Atlantic and Arctic Oceans. These sleek swimmers often hunt for fish and crustaceans at 300 feet (90 meters) and may dive to nearly 1,000 feet (300 meters). They are able to remain submerged for up to 15 minutes. During mating season, females form large colonies on floating ice and give birth to young. Older seals return annually to pack ice to molt. They lose their pelts and top layers of skin and grow a new fur coat every year. Harp seals are sometimes called saddleback seals because of the dark, saddlelike marking on the back and sides of their light yellow or gray bodies of the adults. Baby seals are born on pack ice floating in the North Atlantic and Arctic Oceans. Harp seal mothers are able to identify their babies by their smell. The pups don’t have any blubber at birth, but quickly gain weight nursing on high-fat mother’s milk. When the pups reach about 80 pounds (36 kilograms), their mothers stop nursing them. The pups go without food for about six weeks and can lose about half their body weight until they dive in and begin to hunt for themselves. The young seals are famous for their snowy white coats.

During the mating season, male blue-footed boobies strut around with exaggerated movements that show off their fabulous blue feet. Females tend to pick the males with the bluest feet as their mates. Parents take care of their chicks feeding and protecting them—until they’re about two months old. At that point, young boobies can survive on their own. Blue-footed boobies sleep at night, generally on land, and feed at sea during the day. Sometimes boobies feed in a group. They often fly far out to sea to look for their prey—small fish such as anchovies. The birds either zip underwater for fish from a floating position on the water’s surface or make awesome dives from as high as 80 feet (24 meters) in the air. Once it spots a school of fish, the bird folds those wings back, becoming a streamlined, torpedo-shaped predator. The booby dives into the water among the school of fish, using its long beak to grab dinner.

Jaguars are the largest of South America’s big cats and the third largest cats in the world. Their fur is usually tan or orange with black spots, called „rosettes“ because they are shaped like roses. Some jaguars are so dark they don’t seem to have spots. Unlike many other cats, jaguars do not avoid water; in fact, they are quite good swimmers. Rivers provide prey in the form of fish, turtles, or caimans—small, alligatorlike animals. Jaguars also eat larger animals such as deer, peccaries, capybaras, and tapirs. They sometimes climb trees to prepare an ambush, killing their prey with one powerful bite. Because of their size, strength, and predatory skills, jaguars are considered one of the “big cats.” Tigers, leopards, cheetahs, and cougars are also part of this grouping. Take the big cat quiz to see how much you know about these fierce felines. Then, just for fun, see which wild cat you’re most like with our personality quiz.
