In northern climates they hibernate. In southern climates they do not hibernate. Photos courtesy of Wildlife S. The bears are an endangered species, listed as Vulnerable, and it is illegal to kill them. The Andean bear is the last remaining short-faced bear subfamily Tremarctinae and the closest living relative to the Florida spectacled bear and short-faced bears of the Middle Pleistocene to Late Pleistocene age.
Spectacled bears are the only surviving species of bear native to South America, and the only surviving member of the subfamily Tremarctinae. The Spectacled bear is a mid-sized species of bear. Overall its fur is blackish in color, though bears may vary from jet black to dark brown and to even a reddish hue.
The pattern and extent of pale markings are slightly different on each individual bear and bears can be readily distinguished by this. Males are a third larger than females in dimensions and sometimes twice their weight. Males can weigh — kilograms — lb , and females 35 —82 kilograms 77 — lb. Length can range from to cm 47—79 in , with a tail length of a mere 7 cm 2.
Compared to other living bears, this species has a more rounded face with a relatively short and broad snout. Credit -text- Wikipedia. Photo credits-files from the Wikimedia Commons. Weight: Around lbs kg males ; around lbs kg females. Mother polar bears sleep deeply in their dens, but they are awake for the birth and nursing of their cubs.
Female polar bears reach sexual maturity around four or five years of age. Mating season occurs in the spring, but embryos do not begin to develop until the female enters her den.
Polar bears give birth to one to three cubs during the winter; twins are the most common. Newborn cubs are 12 to 14 inches long and weigh a little more than a pound. In the spring, the mother bear and her cubs will emerge from their den. At the top of the food chain in their polar habitat, these large marine mammals evolved from the smaller brown bear and are well-adapted to the often frigid temperatures of their Arctic homes.
While most polar bears live north of the Arctic Circle, some can be found as far south as Alaska and Hudson Bay, Canada. In colder years when pack ice is heavy, polar bears will even travel as far south as Southern Labrador, Newfoundland and the Gulf of St. Lawrence in Canada, and the Norwegian mainland.
Most years, polar bears stay further north, however, roaming sea ice off the coasts of Canada, Greenland, Russia and some islands north of Norway. It is imperative that people are able to distinguish between the different bear species. In This Section. What People Are Saying. The question is no longer Do animals think?
