Tag: Bears

Bears are carnivoran mammals. Presently, there are only eight species of bears that are extant (still living). There are about 7 (modern) extinct species of bears and many others that have been discovered through scientific research of remains. Bears inhabit a variety of areas mostly in the Nothern Hemisphere. For example, bears are found on the continents of North America, South America, Europe, and Asia.
Modern bears have large bodies and stocky legs. They have long snouts, small rounded ears, and short tails. The polar bear is the largest bear species in existence today and is mostly carnivorous. Other species, like the giant panda, mostly feed on plants (in this case bamboo). The remaining species are omnivorous and readily eat what is available in their surroundings (plant or animal).
Bears usually prefer to be by themselves outside of the mating season. They can ve nocturnal or diurnal. Bears have an excellent sense of smell, are capable runners, swimmers, and some are even adept at climbing. Bears use caves and logs as dens and most species use their dens during winter for hibernation purposes.
