California sea lions live on the western coast of North America from the Baja California peninsula in Mexico to British Columbia. These semi-aquatic mammals feed on fish, squid, and shellfish. They are generally found in open water, where they prefer to fish, but are sometimes found in rivers near the coast as well. These sea lions are an intelligent and social species. They travel in groups of 12 or more, and hang out on man-made structures such as piers and jetties. They gather on remote sandy beaches and rocky areas to breed. During breeding season, males claim and defend their territories. Mothers usually give birth to a single pup after a gestation period of 11 months. The pups are able to swim at birth, although young pups stay on the beach rather than venturing into the water. California sea lions are usually dark brown, although some females can appear tan. Pups are born with a dark, black-brown coat. The California sea lion is faster than any other sea lion or seal in the world. They can dive to depths of 900 feet, and can stay underwater for nearly ten minutes without breathing by slowing their heart rate. Text by Sara Zeglin / NGS Staff

These horses are able to detect smell and sound from great distances. They are smaller than most domestic horse species and have stocky bodies, large heads, thick necks, upright manes, and a dark stripe down their backs. Their underbellies and muzzles have pale white markings, and their legs are short and slender. Przewalski’s horses can use their sharp hooves to get at water in the ground. They eat mainly grass, as well as plants and fruit, and sometimes bark, leaves, and buds. Horses are an important part of Mongolian culture. However, Przewalski’s horses have not been seen in the wild since 1968. Excessive hunting by people and the loss of grazing and watering sites to domestic animals like cattle and sheep lowered the horses‘ numbers dramatically. In the late 19th and early 20th centuries, several wild Przewalski’s horses were caught and bred in captivity. Thirteen of those horses are the original ancestors of today’s captive population. Today there are about 1,200 Przewalski’s horses living in zoos, private preserves, and protected areas in Mongolia. Small groups are gradually being reintroduced into the wild to once again roam the grasslands of Mongolia.

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.

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.
