Urasus arctos horribilis
Grizzly bears are specially adapted to survive the changing seasons. During warmer months, they eat massive amounts of food so they can live off during the winter, when food is scarce.
WHY IT IS ENDANGERED
Between 1800 and 1975, grizzly bear populations in the lower 48 states decreased from estamates or more than 100,000 to less 1000.The grizzly was eliminated from much of the west by the late 1800's.
Some grizzly bears are accidentally killed by huters who mistake them for black bears, which is legal.
