Octopus | National Geographic Kids

https://kids.nationalgeographic.com/animals/invertebrates/facts/octopus

Octopuses are sea animals famous for their rounded bodies, bulging eyes, and eight long arms. They live in all the world’s oceans but are especially abundant in warm, tropical waters. Octopuses, like their cousin, the squid, are often considered “monsters of the deep,” though some species, or types, occupy relatively shallow waters. Most octopuses stay along the ocean’s floor, although some species are pelagic, which means they live near the water’s surface. Other octopus species live in deep, dark waters, rising from below at dawn and dusk to search for food. Crabs, shrimps, and lobsters rank among their favorite foods, though some can attack larger prey, like sharks. Octopuses typically drop down on their prey from above and, using powerful suctions that line their arms, pull the animal into their mouth. The octopus performs its famous backward swim by blasting water through a muscular tube on the body called a siphon. Octopuses also crawl along the ocean’s floor, tucking their arms into small openings to search for food. Seals, whales, and large fish prey on octopuses. If threatened, octopuses shoot an inky fluid that darkens the water, confusing the aggressor. The octopus can also change to gray, brown, pink, blue, or green to blend in with its surroundings. Octopuses may also change color as a way to communicate with other octopuses. Octopuses are solitary creatures that live alone in dens built from rocks, which the octopus moves into place using its powerful arms. Octopuses sometimes even fashion a rock “door” for their den that pulls closed when the octopus is safely inside.

Red-Tailed Hawk | National Geographic Kids

https://kids.nationalgeographic.com/animals/birds/facts/red-tailed-hawk

The red-tailed hawk is a top predator. The hawks use tall perches to spot their prey in the open spaces next to highways. Red-tailed hawks also hunt from the air. As they circle and soar, they can spot a mouse from 100 feet (30 meters) up in the air—about ten stories high. When a red-tailed hawk spots a rodent, rabbit, lizard, or other prey scurrying, it swoops down and grabs its meal in its talons—the big claws on its feet. Once the hawk grabs its prey, it usually flies back up to its perch to eat it. They were named for the variety that has a brick-red tail. Male and female red-tailed hawks basically look alike, though the females are larger. Red-tailed hawks often mate for life. The pair makes a stick nest in a tree, high above the ground. They will use the nest year after year, so it grows bigger and bigger. The female hawk lays one to five eggs—which are white with brown spots. The parents take turns sitting on the eggs, keeping them warm and safe. Baby red-tailed hawks are covered with white, downy feathers. The hawk parents feed their young until the young birds can leave the nest, usually when they’re about six weeks old.

American Alligator | National Geographic Kids

https://kids.nationalgeographic.com/animals/reptiles/facts/american-alligator

American alligators once faced extinction. The United States Fish and Wildlife Service placed them on the endangered species list in 1967. Fortunately, the legal protection worked. Just 20 years later, American alligators were taken off the list. Brought back from the brink of extinction, over a million of these reptiles survive today. Now the main threat to alligators is habitat destruction, caused by such human activities as draining and developing wetlands. American alligators live in the wild in the southeastern United States. You’re most likely to spot them in Florida and Louisiana, where they live in rivers, lakes, ponds, swamps, bayous, and marshes. These reptiles are kind of clumsy on land, but they’re built for life in the water. Great swimmers, they are equipped with webbed feet and strong tails that propel them through the water. An average male American alligator is 10 to 15 feet (three to five meters) long. Half of its length is its massive, strong tail. An alligator can weigh as much as half a ton (1,000 pounds), but an average male weighs between 500 and 600 pounds (227 to 272 kilograms). Females are usually smaller than males. As big and ferocious as the female alligator may look, she is a gentle mother. A mother alligator makes a nest on shore, where she lays her eggs. Then she guards her eggs until they’re ready to hatch. At that point the babies start to make noises, and their mother hears her little ones‘ peeps as they break out of the eggs. She gently carries them—in her mouth—to the water nearby. Newly hatched young are only about six to eight inches (15 to 20 centimeters) long, and very vulnerable. Their mother protects them from predators, which include raccoons, bobcats, birds, and even other alligators. The young alligators stay with their mother for up to two years. After that, they’re able to fend for themselves.

Polar Bear photos, facts, and map | National Geographic Kids

https://kids.nationalgeographic.com/animals/mammals/facts/polar-bear

Polar bears live along shores and on sea ice in the icy cold Arctic. When sea ice forms over the ocean in cold weather, many polar bears, except pregnant females, head out onto the ice to hunt seals. Polar bears primarily eat seals. Polar bears often rest silently at a seal’s breathing hole in the ice, waiting for a seal in the water to surface. A polar bear may also hunt by swimming beneath the ice. But climate change is making it harder for polar bears to hunt. Ice melts earlier and re-forms later than it has in the past. Without the sea ice, the polar bear must scavenge for other, less nutritious food. Polar bears roam the Arctic ice sheets and swim in that region’s coastal waters. They are very strong swimmers, and their large front paws, which they use to paddle, are slightly webbed. Some polar bears have been seen swimming hundreds of miles from land—though they probably cover most of that distance by floating on sheets of ice. In fall pregnant polar bears make dens in earth and snowbanks, where they’ll stay through the winter and give birth to one to three cubs. In spring the mother emerges from her den followed by her cubs. During that time she will protect them and teach them how to hunt. The U.S., Canada, Denmark, Norway, and Russia signed an agreement in 1973 to protect polar bears.

Leatherback Sea Turtles | National Geographic Kids

https://kids.nationalgeographic.com/animals/reptiles/facts/leatherback-sea-turtle

Leatherback sea turtles are the biggest turtles on Earth. An adult leatherback sea turtle is generally longer than an average-size man is tall. Unlike other species of sea turtles, which have hard shells, the leatherback’s shell is leathery; it feels almost rubbery. The shell is black, often speckled with white or yellow spots. These huge reptiles lived 100 million years ago—during the age of dinosaurs—but their future is uncertain. Leatherbacks are one of the more endangered creatures on Earth. They are often caught by accident in fishing nets. Stuck underwater, they drown. Sea turtle nesting habitats are also being destroyed, and the eggs they do lay are illegally collected by people for food. Newly hatched sea turtles instinctively head from the nest to the sea, but in areas where people live, the hatchlings often become confused by lights from houses built along shore. Instead of heading to sea, they head toward the lights. Another hazard for sea turtles is floating plastic trash, which they often mistake for jellyfish, their main food. Leatherbacks must breathe air at the surface, but can stay underwater for up to 35 minutes at a time. Only females ever leave the ocean. During nesting season, the female comes ashore on a sandy beach, where she digs a hole. She lays about 100 eggs in the hole, covers them with sand, and heads back to sea. Sea turtles do not guard their nests, so the babies are on their own. The eggs take about two months to hatch. The tiny hatchlings are only 2 to 3 inches (5 to 8 centimeters) long. As soon as they hatch, they dig their way out of the sandy nest and scurry across the beach to the sea. Gulls and other birds often scoop up the hatchlings before they make it to the water. Other predators, such as large fish, await those lucky enough to make it into the sea.

Kangaroo facts and photos | National Geographic Kids

https://kids.nationalgeographic.com/animals/mammals/facts/kangaroo

Kangaroos possess powerful hind legs, a long, strong tail, and small front legs. Kangaroos belong to the animal family Macropus, literally „big foot.“ Thanks to their large feet, kangaroos can leap some 30 feet (9 meters) in a single bound, and travel more than 30 miles (48 kilometers) per hour. Kangaroos use their strong tails for balance while jumping. They are the tallest of all marsupials, standing over 6 feet (2 meters) tall. Kangaroos live in Eastern Australia. They live in small groups called troops or herds (“mobs” by Australians), typically made up of 50 or more animals. If threatened, kangaroos pound the ground with their strong feet in warning. Fighting kangaroos kick opponents, and sometimes bite. Female kangaroos sport a pouch on their belly, made by a fold in the skin, to cradle baby kangaroos called joeys. Newborn joeys are just one inch long (2.5 centimeters) at birth, or about the size of a grape. After birth, joeys travel, unassisted, through their mom’s thick fur to the comfort and safety of the pouch. A newborn joey can’t suckle or swallow, so the kangaroo mom uses her muscles to pump milk down its throat. At around 4 months, the joey emerges from the pouch for short trips and to graze on grass and small shrubs. At 10 months, the joey is mature enough to leave the pouch for good. Besides humans and wild dogs called dingoes, kangaroos face few natural predators. Heat, drought, and hunger due to vanishing habitat are the biggest dangers kangaroos face.

Ring-Tailed Lemur | National Geographic Kids

https://kids.nationalgeographic.com/animals/mammals/facts/ring-tailed-lemur

If you were to check in one morning on a group of ring-tailed lemurs, you’d likely see them sitting on the ground, facing the sun with their arms outspread. Ring-tailed lemurs often spend hours soaking up the warmth of the sun. And they do it in a group, since they’re social animals. In a troop, or group, of ring-tailed lemurs, which typically numbers between 15 and 20 individuals, females rule. If a squabble breaks out between a male and a female, the female lemur always wins the argument. Lemur troops establish territories, which they defend against other troops. The male lemurs tend to hang back during battles. Male ring-tailed lemurs come and go from one troop to another, while females stay with the one in which they were born. As the troop moves from feeding site to feeding site, the core group of females settles into the best feeding spot (generally a good tree) and eats first. The males wait for them to finish or feed in a less desired tree nearby. The same goes for often hard-to-find water which collects in tree hollows. Some female lemurs are dominant over the other females and higher-ranking males strut around with their heads and tails held high, while the lower-ranked lemurs keep their tails and heads down.
