Beavers are the largest rodents (gnawing animals) in North America and the second largest in the world, behind the South American capybara. Beavers are powerful swimmers that can swim underwater for up to 15 minutes. As the beaver dips underwater, the nose and ears shut to keep water out. Transparent inner eyelids also close over each eye to help the beaver see.

Black-tailed jackrabbits are not actually rabbits, but are hares. Hares are born with fur and are larger than rabbits. They usually have taller hind legs and longer ears. These speedy animals are capable of reaching 40 miles (64 kilometers) an hour. They have powerful hind legs that can propel them on leaps of more than 10 feet (3 meters) . They use these leaps and a zigzag running style to evade their many predators, including coyotes. Jackrabbits produce a lot of young called leverets or bunnies. Females give birth to several litters a year, each with one to six young. The young mature quickly and require little care from their mothers. While the endangered status of most species is least concern, the Tehuantepec jackrabbit is considered near threatened. Other species of jackrabbits live in Mexico, the United States, and Canada.

Although native to Europe, earthworms are found throughout North America and western Asia. They do not live in deserts or regions where there is permafrost or permanent snow and ice. Typically only a few inches (7 or 8 centimeters) long, some members of this species have been known to grow to a snakelike 14 inches (35 centimeters). Earthworms‘ bodies are made up of ringlike segments called annuli. These segments are covered in setae, or small bristles, which the worm uses to move and burrow. These terrestrial worms typically dwell in soil and moist leaf litter. Their bodies are characterized by a „tube within a tube“ construction, with an outer muscular body wall surrounding a digestive tract that begins with the mouth in the first segment. As they burrow, they consume soil, extracting nutrients from decomposing organic matter like leaves and roots. Earthworms are vital to soil health and to plants growing in it because they transport nutrients and minerals from below to the surface via their waste. An earthworm can eat up to a third of its body weight in a day.

Co-what-i? You may not be familiar with this fur ball, which inhabits parts of South America, Central America, and North America. But you no doubt know about the mammal’s famous family. The coati is closely related to the raccoon. And like its cousin, this mammal is the size of a large house cat, has a ringed tail, and hangs out in trees. SNOOZE AND CHEWS Unlike the nocturnal raccoon, which is active at night, the coati mostly gets its z’s when it’s dark. These animals turn treetops into bedrooms, even building comfy twig-and-leaf nests in branches for their babies. As a coati sleeps, it tucks its nose into its belly. During the day, the coati is all about snacking. It uses its long, flexible nose to probe gaps between rocks and search under piles of leaves for grub. Coatis eat insects, fruit, rodents, lizards, and small snakes. MAKE SOME NOISE Female and baby coatis eat, sleep, and travel in packs of about 30. At age two, males leave to live on their own. In groups these animals are chatty—they click, grunt, whistle, and bark as they forage for food. So while it may not be as well known as its raccoon relatives, the coati definitely lets you know it’s there. Text by April Capochino Myers

Bull sharks are among the most dangerous sharks in the world, according to many experts. This is because they’re an aggressive species of shark, and they tend to hunt in waters where people often swim: along tropical shorelines. Bull sharks live throughout the world, in shallow, warm ocean waters. They’ve been known to swim up into freshwater rivers. Humans are not part of a bull shark’s normal prey. Bull sharks will eat almost anything, but their diet consists mainly of fish. They also sometimes eat dolphins and sea turtles. Bull sharks even eat other sharks. They hunt during the day and at night. Sharks must keep salt in their bodies to survive, and most can live only in salt water. But bull sharks have developed special adaptations—the way their kidneys function and special glands near their tails—that help them keep salt in their bodies even when they’re in freshwater. Scientists are still studying these sharks to figure out why they developed this unusual ability.

Caribou are mammals that live in the northern regions of Europe, North America, Asia, and Greenland. When snow begins to fall, caribou move south and travel to more sheltered climes where they can feed on moss or lichens. These members of the deer family dig for food using their large hooves. The underside of each hoof is hollowed out like a big scoop and allows the caribou to dig through snow in search of food. Caribou trek north in the summer in one of the largest animal migrations on Earth. They travel more than 600 miles (965 kilometers) along well-traveled routes. They spend the summer feeding on grasses, mushrooms, and plants in the tundra. They begin to move south in the winter and over one year they will have migrated over 1,600 miles (2,574 kilometers). One adult caribou eats about 12 pounds (5 kilograms) of food each day. Caribou are hunted by indigenous northern people throughout much of their range. Woodland caribou are listed as endangered, but other caribou populations are stable.
