When a great white shark is born, along with up to a dozen siblings, it immediately swims away from its mother. Born on the east and west coasts of North America, the south of Africa and southwest Australia, baby sharks are on their own right from the start. Their mother may see them only as prey. At birth the baby shark is already about 5 feet (1.5 meters) long; as it grows it may reach a length up to four times that. The pup (which is what a baby shark is called) will live its life at the top of the ocean’s food chain. But before it grows larger, the pup must avoid predators bigger than it is—including other great white sharks. Many baby sharks do not survive their first year. Young great white sharks eat fish (including other sharks) and rays. As they grow, the sharks’ favorite prey becomes sea mammals, especially sea lions and seals. Sharks count on the element of surprise as they hunt. When they see a seal at the surface of the water, sharks will often position themselves underneath the seal. Using their tails as propellers, they swim upward at a fast sprint, burst out of the water in a leap called a breach, and fall back into the water with the seal in their mouths. They can smell a single drop of blood from up to a third of a mile (0.53 kilometers) away. Sharks don’t chew their food; they rip off chunks of meat and swallow them whole. They can last a month or two without another big meal.

Walruses have long tusks and a prominent mustache. These large marine mammals are found near the Arctic Circle. They are extremely social and snort and bellow loudly at their companions. During the mating season they are quite aggressive. Walruses have wrinkled brown and pink skin, long, coarse whiskers, flat flippers, and lots of blubber on their bodies to keep them warm in the cold Arctic water. They can slow down their heartbeat to withstand the chilly water temperatures and to help them stay under water for as long as ten minutes. Their long tusks are useful in many ways. They use them to pull their enormous bodies out of frigid waters, and seem to walk on their tusks. They also use their tusks to break breathing holes into ice from below. Tusks are found on both males and females and keep growing throughout their lives. These tusks are actually canine teeth and can grow to be about three feet (one meter) long. Their whiskers are very sensitive and help the walruses find their favorite meals, such as clams, way down in the deep, dark ocean floor. Their whiskers are longest at the corners of their mouth. Only Native Americans are currently allowed to hunt walruses, as the species‘ survival was threatened by past overhunting. Hunters in the 18th and 19th centuries captured walruses for their tusks, oil, skin, and meat and now there aren’t any walruses in the Gulf of St. Lawrence and around Sable Island, off the coast of Nova Scotia.

Is this animal a dinosaur or a bird? Maybe it’s both!

The Gila monster is one of only a few poisonous lizards in the world. The Gila (pronounced HEE-luh) is the largest lizard native to the United States. Their black bodies are covered in beadlike scales with bright spots, blotches, or bands of pink, orange, or yellow, which probably warn other animals to stay away. Their bulky bodies, slow-moving stride, thick forked tongue, and snorting hisses reinforce the name Gila monster. They live in the dry, arid regions such as the Mojave, Sonoran, and Chihuahuan Deserts of the southwestern U.S. and northwestern Mexico. They are named after the Arizona Gila River Basin, where they were first discovered. Gila monsters are more likely to use their venom on a predator than on prey. They clamp their jaws down with the power of a vise grip. Then the venom in their bottom jaw flows through their grooved teeth into the victim. Although the Gila’s bite is extremely painful, no human death has been reported. Gilas are sluggish creatures that feed primarily on eggs raided from bird nests and newborn mammals, such as rabbits and squirrels. They sometimes eat quail eggs whole without crushing the shells. They spend about 95 percent of their time underground and emerge only to hunt for food or to take a sunbath. They don’t need to eat very often because they can store fat in their large tails.

Mallard ducks are the most common and recognizable wild ducks in the Northern Hemisphere. You’ll find them near ponds, marshes, streams, and lakes, where they feed on plants, invertebrates, fish, and insects. Mallards are dabbling, or surface-feeding, ducks because they eat by tipping underwater for food—head down, feet and tail in the air—rather than diving. Mallards also forage and graze for food on land. The male mallard duck, called a drake, sports a glossy green head, a white ring around its neck and a rich, chestnut-brown breast. The mottled brown female mallard looks downright dull next to the male’s showy feathers. The mallard duck’s outer feathers are waterproof, thanks to oil that’s secreted from a gland near the tail. Beneath this tightly packed waterproof layer of feathers lies a soft, warm layer of feathers called down. Twice a year, mallards molt, or shed, their flight feathers, temporarily grounding the birds for several weeks until the feathers grow back. Mallards fly in groups called flocks. Like most migratory birds, mallards fly in the famous V formation. During winter migration, mallards fly south in search of warm weather, often resting at the same spots year after year. Migrating mallards can travel great distances, relying on rivers, coasts, and valleys to find their way. A female mallard lays up to a dozen eggs in nests on the ground near water, often in a small depression or tree hole. She lines the nest with warm down plucked from her undercoat. Soon after birth, baby ducks, called ducklings, open their eyes. A little more than a day after hatching, ducklings can run, swim, and forage for food on their own. They stay in the nest for less than a month. A group of ducklings is called a brood. Outside the nest, the brood sticks close by the mother for safety, often following behind her in a neat, single-file line.

Female black widows are shiny black, with a red-orange hourglass pattern on their abdomen. Male black widows are not black, but brown or gray with small red spots. Black widows are poisonous arachnids—animals that have a skeleton outside their body, a segmented body, and eight jointed legs. They are not insects. Their deadly poison is said to be 15 times stronger than rattlesnake venom. Black widows use a silk-like substance to weave tangled-looking webs, typically close to the ground in covered or dark places, such as near drain pipes or under logs. The female hangs upside down in the web to await her prey, exposing her bright markings as a warning to potential predators. The black widow senses vibrations to the web. When an unlucky intruder gets trapped, the spider immediately begins weaving its glue-like webbing around it. Insects such as flies, mosquitoes, or even larger prey like grasshoppers are typically caught. Once captured, the black widow injects its victims with poison, paralyzing them. The tips of the black widow’s legs are coated with an oily substance that prevents the black widow from getting caught in its own web. Adult male and female black widows live solitary lives, meeting only to breed. The female black widow lays approximately 200 eggs. The eggs incubate for some 20 days in a small, round papery sac that’s attached to the mother’s web. After hatching, the baby spiders stay in the cocoon for up to one month. Three species of poisonous North American spiders carry the common name black widow under the genus Latrodectus. Each species occupies a distinct region of North America, as their names suggest: Eastern black widows (L. mactans), northern black widows (L. variolus), and western black widows (L. hesperus). These three species have very similar physical and behavioral characteristics. The name “black widow” comes from the female’s habit of eating the male after mating.

 The female black widow is approximately 1.5 inches (38 millimeters) long. The male is about half the female’s size.

 The black widow is prey for birds and other spiders. Although poisonous, the black widow is not considered aggressive unless threatened. In fact, the male black widow is reclusive and hardly ever seen by humans. While the black widow’s poison is rarely fatal to humans, it can cause severe pain and nausea.

Amphibians are cold-blooded vertebrates (vertebrates have backbones) that don’t have scales. They live part of their lives in water and part on land.
