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.

A hungry bobcat crouches behind a bush, looking at the field beyond its leafy hideaway. Suddenly, a squirrel darts across the ground. As the squirrel draws near, the cat leaps from the bush and scoops up the prey in its mouth. It’s dinnertime.

These beautifully colored sea turtles got their name because their oversized head sort of looks like a big log. Within their heads are powerful jaws, which loggerheads use for crushing prey like conchs, horseshoe crabs, and other animals with hard shells. They also eat softer foods like jellyfish, fish, seaweed, and a brown algae called sargassum. Loggerheads live in oceans all over the world, except in the coldest seas. There are more loggerheads in the waters of the United States than any other species of sea turtle. A female loggerhead sea turtle may travel thousands of miles to return to the beach where she hatched as a baby to lay her own eggs as an adult. A loggerhead female generally nests every two to three years. On average, she’ll lay eggs four times in one nesting season. Each time, she comes ashore and uses her front flippers to clear a spot in dry sand. Then she uses her hind flippers to dig her nesting hole and gently lay her eggs. Those that remain undisturbed hatch about 60 days later. Hatchlings dig their way up through the sand toward the surface and wait just underneath the last layer of sand until nightfall. Once cooler temperatures signal that the sun has set, the hatchlings pop the rest of the way out and scurry toward the ocean avoiding raccoons, crabs, birds, and other predators.

A rainbow-colored crustacean skitters along the ocean floor, adding a splash of brightness to the murky setting. The animal’s narrow, hard-shelled body sports orange, green, red, and blue hues. Known as the peacock mantis shrimp, this beautiful, seven-inch-long critter looks harmless. But the marine animal packs a punch—literally. SHRIMP SMACKDOWN Peacock mantis shrimp mostly live in shallow parts of the Indian and Pacific Oceans. The crustacean spends much of its time looking for crabs and mollusks to eat. When it finds a delicious-looking snack, the animal goes into full-on boxer mode. Springing out one of its club-like front claws, the animal delivers a swift punch to its prey. The punch is 50 times faster than the blink of an eye and strong enough to break glass! These shrimp also rely on their sparing moves to keep enemies away from burrows in the ocean floor that they use as shelters. Hovering at the opening of its burrow, a peacock mantis shrimp will strike at intruders that come too close. EYES ON THE PRIZE The crustacean has another eye-popping feature in addition to its strong punch. Its eyes—which protrude from its head and move independently—can see in two different directions at once. They can also detect colors that humans are unable to see. It’s easy to be floored by this animal’s cool traits! Watch a video of the peacock mantis shrimp. Text by Andrea Silen, NGS Staff

Giraffes grow about 4 feet (1.2 meters) in their first year of life. A newborn giraffe is about 6 feet (1.9 meters) tall at birth and weighs about 150 pounds (68 kilograms). Many young giraffes, called calves, die from lion attacks during their first year of life. Once a giraffe reaches adulthood its height is often enough to protect it from lions. Adult giraffes, however, must still be careful of lions when they are bending down to drink water or rest. Usually giraffes will drink or rest in shifts so that at least one giraffe is always on the lookout for approaching predators. The giraffes‘ height and excellent vision give them a wide view of the grasslands where they live, making it easy to spot predators from a distance. Some scientists believe that other animals—such as zebras, antelope, and wildebeests—often congregate near giraffes to take advantage of their ability to see danger from a distance. The giraffe could be considered the early warning system of the African grasslands.

Flamingos are famous for their bright pink feathers, stilt-like legs, and S-shaped neck. When a flamingo spots potential dinner—favorite foods include shrimp, snails, and plantlike water organisms called algae—it plunges its head into the water, twists it upside down, and scoops the fish using its upper beak like a shovel. They are able to „run“ on water, thanks to their webbed feet, to gain speed before lifting up into the sky. Flamingos build nests that look like mounds of mud along waterways. At the top of the mound, in a shallow hole, the female lays one egg. The parents take turns sitting on the egg to keep it warm. After about 30 days, the egg hatches. Flamingo young are born white, with soft, downy feathers and a straight bill. The bill gradually curves downward as the flamingo matures. Both parents take care of the newborn flamingo, feeding it a fluid produced in their digestive systems. The young leave the nest after about five days to join other young flamingos in small groups, returning to the parents for food. The parents identify their chick by its voice. After about three weeks, the adults herd young flamingos into large groups called crèches where they start to look for food on their own. Most flamingo species are not endangered, although the Andean flamingo is listed as Vulnerable, and the Chilean, Lesser, and Puna flamingos are Near Threatened.

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.
