North American River Otter

Ranging over much of North America, the river otter survives anywhere with access to abundant prey and clean water. With a streamlined body, webbed feet, muscular tail, flexible body, and waterproof fur, otters are designed for swimming in search of fish, crayfish, and other aquatic creatures to eat.

Two-toed Sloth

The sloth is not lazy, just slow. Instead of foraging all day long to get enough energy from the leaves it eats, the sloth conserves energy by being inactive. This requires few heavy muscles, making the sloth light enough to climb high on thin branches where it can feed without worrying about jaguars.

Naked Mole-rat

Living in large colonies, the nearly blind naked mole-rat spends its entire life excavating tunnels underground in search of roots and tubers.  The colony is led by a single breeding female called the queen that mates with several males. All other colony  members forgo breeding to raise the pups, forage, and maintain the burrow.


The solitary coatimundi, often called coati, is the male, while the females live in highly social groups or bands. Living in a group affords the coatis greater protection as there are more eyes to watch out for predators and they can band together to fight off an attack.

Feather-tailed Glider

Stretching out its patagium, a thin, furred membrane that extends from wrist to knee, the feather-tailed glider glides up to 65 feet from tree to tree like a parachute. Its tail resembles a feather with stiff hairs on either side, which helps the glider steer. Sharp claws dig into the tree’s bark upon landing.

Parma Wallaby

Kangaroos and wallabies are in the same family, with wallabies as the smaller of the two. When a baby wallaby, called a joey, is born it climbs into a pouch on its mother’s belly where it stays safe and hidden for the first six or seven months of its life.

Bennett’s Wallaby

Kangaroos and wallabies are in the same family, with wallabies as the smaller of the two. Bennett’s wallaby, also called the red-necked wallaby, is generally solitary, though loose mobs may come together while foraging at night. During the day, the wallaby rests among dense patches of shrubs within the forest.

Yellow-backed Duiker

Living in thick forest, these small antelopes rely on scents to communicate. Duikers rub scent glands under their eyes on branches to mark their territory, on mates during courtship, and on young to familiarize them with the scent. Males will rub the glands on each other aggressively in competition.


The takin belongs to a group of large, hoofed mammals called the goat antelopes, which share characteristics with both goats and antelopes. Living high up in the mountains, the takin wears a thick coat of dark, shaggy fur to keep warm in winter, similar to its more well-known relative, the musk ox.

Red River Hog

Living in social groups called sounders, red river hogs barrel their way through the forest in search of food. Using their strong snouts and sharp tusks to bulldoze through the leaf litter and soil, they dig up a dinner of roots, bulbs, other plants and small animals.
