The Madagascar hissing cockroach is all hiss and no sting. Its alarm hiss, which sounds like a loud snake hiss, is the cockroach’s attempt to scare off intruders. The male cockroach also uses distinct hisses to attract a mate and to intimidate other male cockroaches. When defending their territory from other males, these cockroaches will hiss, push, and shove, and stand on their “toes” to show who’s boss. The male that is larger and hisses more usually wins. It is one of the largest species of cockroach in the world—adults grow to be between two and four inches (5.1 and 10.2 centimeters) long! With their thick and waxy exoskeletons, Madagascar hissing cockroaches may look like big pests, but they’re actually important to the health of the rain forest. They are detritivores, which means they eat decaying plant material and animal carcasses. They recycle nutrients back into the ecosystem.

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.

These frogs are considered one of Earth’s most toxic, or poisonous, species. For example, the golden poison dart frog has enough poison to kill 20,000 mice. With a range of bright colors—yellows, oranges, reds, greens, blues—they aren’t just big show-offs either. Those colorful designs tell potential predators, „I’m toxic. Don’t eat me.“ Scientists think that poison dart frogs get their toxicity from some of the insects they eat. How do poison dart frogs capture their prey? Slurp! With a long, sticky tongue that darts out and zaps the unsuspecting bug! The frogs eat many kinds of small insects, including fruit flies, ants, termites, young crickets, and tiny beetles, which are the ones scientists think may be responsible for the frogs‘ toxicity. Poison dart frogs live in the rain forests of Central and South America.

Christmas Island red crabs are famous throughout Australia and the world for their bright red color and for their spectacular annual migration to the sea. Millions of crabs become rivers of red as they move from the island’s interior rainforests to the ocean to breed and lay eggs. During migration, red crabs climb over and around obstacles in their way, following the same migration paths every year. Christmas Island red crabs live on Christmas Island in the Indian Ocean off Australia’s northern coast, about 240 miles (380 kilometers) south of Java, Indonesia. Red crabs must keep their bodies moist, so they wait for the rainy season to provide conditions that are ideal for the difficult journey. A single female can lay up to 100,000 eggs.

Picture a camel. Now take away a hump (or two). Finally, shrink it down in size and place it in South America, living as far south as Tierra del Fuego. What do you end up with? A guanaco. Guanacos are related to camels, as are vicunas, llamas, and alpacas. But they live in South America, while camels are found in Africa and Asia. Guanacos and vicunas are wild animals, but llamas and alpacas have been domesticated, like cats and dogs, and were probably bred from guanacos. They’re slender animals with pale brown backs, white undersides, short tails, large heads, very long necks, and big, pointed ears. They live in groups of up to ten females, their young, and a dominant male adult. Unattached bachelor males form herds of their own—these can include as many as 50 or more animals. When a female guanaco gives birth, her newborn, known as a chulengo, is able to walk immediately. Chulengos can keep up with the herd right away. Guanacos live on land high in the Andes mountains—up to 13,000 feet (3,962 meters) above sea level—as well as on the lower plateaus, plains, and coastlines of Peru, Chile, and Argentina. Guanacos were once over hunted for their thick, warm wool. Now they thrive in areas protected by law.

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.

Jellyfish have drifted along on ocean currents for millions of years, even before dinosaurs lived on the Earth. The jellylike creatures pulse along on ocean currents and are abundant in cold and warm ocean water, in deep water, and along coastlines. But despite their name, jellyfish aren’t actually fish—they’re invertebrates, or animals with no backbones. Jellyfish have tiny stinging cells in their tentacles to stun or paralyze their prey before they eat them. Inside their bell-shaped body is an opening that is its mouth. They eat and discard waste from this opening. As jellyfish squirt water from their mouths they are propelled forward. Tentacles hang down from the smooth baglike body and sting their prey. Jellyfish stings can be painful to humans and sometimes very dangerous. But jellyfish don’t purposely attack humans. Most stings occur when people accidentally touch a jellyfish, but if the sting is from a dangerous species, it can be deadly. Jellyfish digest their food very quickly. They wouldn’t be able to float if they had to carry a large, undigested meal around. They dine on fish, shrimp, crabs and tiny plants. Sea turtles relish the taste of jellyfish. Some jellyfish are clear, but others are in vibrant colors such as pink, yellow, blue, and purple, and often are luminescent. The Chinese have fished jellyfish for 1,700 years. They are considered a delicacy and are used in Chinese medicine.

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.
