otters, and wolverines. They are perhaps best know for their dark brown fur, which turns white at the chin and runs to black at the tips of their tails. They have long, slender torsos atop short legs. Full-grown females are usually 17 to 21 inches long and weigh 1.25 to 1.75 pounds, while full-grown males are usually 21 to 24 inches in length and weigh 2 to 3.75 pounds.
fox and the gray fox. Gray foxes are known to be native to North America, but whether the red fox was ever native is a subject of debate. It seems likely that the red fox was, probably arriving by the same land bridge used by the first humans during the last Ice Age. Many red foxes were brought to North America from Europe in the 1700s for sport hunting, and they remain popular prey for hunters and trappers.
to 15 years in the wild. Social “chatterboxes,” these sensitive, nocturnal animals can spend all night long just talking to one another. Fastidiously clean, they require frequent dust baths to care for their extremely dense fur. These “fluff fests” also provide invaluable moments of comfort and entertainment—moments that are denied to caged chinchillas who are cruelly “farmed” fur.
4.Rabbit:Few animals are as content to sit unmoving for as long as rabbits are. As prey animals, rabbits go to extremes not to advertise themselves as available to be eaten—but that isn't to say they don't let their guard down once in a while. If lucky, the patient observer may see them in the early morning or evening hours in spirited and spontaneous chases of other rabbits, or energetically hopping and leaping about—revealing this animal's playful nature.
like a human, has performed one of North America's most remarkable ecological feats: recovery from near extinction. Beavers are extremely gentle, family-oriented animals who mate for life and remain life-long friends with their children. The second-largest rodent in the world, beavers can live 19 years, reach 60 pounds, and grow up to 4 feet long.
marsupial found north of Mexico. Marsupials are distinguished by their unique mode of reproduction: the young are born in an almost embryonic form and make their way to the pouch in their mother's abdomen, where they are nourished for what in other mammals would be most of the gestational period.
animal's unmistakable eau de parfum. Which is too bad, because skunk spray has given the wrong impression about these gentle, non-aggressive creatures. 9.SealTrue seals (a group that doesn't include the fur seal) belong to the family Phocidae. Seals
lack ear flaps and the ability to rotate their hind flippers forward to walk on land, which sea lions can do. Instead they pull themselves forward by their fore flippers, dragging their hind flippers behind them, with an inchworm-like motion. In the water, however, they are amazingly graceful, using their hind flippers in a sculling motion to propel themselves while steering with their front flippers. Some species are deep divers—the northern elephant seal dives regularly to approximately 2500 feet and stays under routinely for 20-30 minutes per dive.
local names), is one of the most widely distributed of all mammals—some say second only to humans. They have adapted to climates as different as deserts, the Arctic tundra, and forests. 11.Black Bear: American black bears (Ursus americanus) are usually true to their name, but you
might spot one who is brown, reddish, yellowish, or even cream-colored. They are the most widely distributed and smallest of the three bears found in North America. The other two, the polar bear and the grizzly bear, are much more restricted in their distribution.
inches long and weigh approximately five pounds. Adult males grow to be about 58 inches long and weigh 60Ð85 pounds. Unlike other marine mammals, sea otters do not have a protective layer of blubber to shield them from cold water. To compensate, they have extremely thick fur that traps warm air between hairs and insulates the body.
rotate their hind flippers forward, giving them a somewhat ungainly, but very agile, gait on land. These are the "circus seals"—the ones seen in circuses and aquaria—able to stand on their fore flippers and climb stairs. In the water, sea lions and fur seals use their fore flippers to propel themselves, with a wing-like flying motion, using their hind flippers to steer (the exact opposite of true seals).
