I think it's fairly evident that bears still have muscles and that the explanation given in this article (along the lines of, "This is why bears no longer have sinews!") is laughable. I'm going to remove the link to prevent confusion, though perhaps it could be linked instead to something that makes sense.
Relying as they do on strength rather than speed, bears have relatively short limbs with thick bones to support their bulk. The shoulder blades and the pelvis are correspondingly massive. The limbs are much straighter than those of the big cats as there is no need for them to flex in the same way due to the differences in their gait. The strong ...
Brown bears have the broadest skull of any extant ursine bear. [43] The width of the zygomatic arches in males is 17.5 to 27.7 cm (6.9 to 10.9 in), and 14.7 to 24.7 cm (5.8 to 9.7 in) in females. [49] Brown bears have strong jaws: the incisors and canine teeth are large, with the lower canines being strongly curved. The first three molars of ...
Bears also use water sources for relaxation and recreation, especially in the hot summer months, whether it’s a large pond or river, a small stream, or even a simple tub. Bears have been known ...
Bears and many other animals like skunks, raccoons, and even birds do go into a deep sleep - torpor - but for much shorter amounts of time; only up to a few hours or a day at most. As they sleep ...
Biologists estimate that there are approximately 20,000 black bears in Washington.
Family Ursidae (bears) is the largest of all the land caniforms. Eight species are recognized, divided into five genera. They range from the large polar bear (350–680 kilograms (770–1,500 lb) in males) to the small sun bear (30–60 kilograms (66–132 lb) in males) and from the endangered giant panda to the very common black bear. Common ...
Several studies have been conducted on the genetic history of the grizzly bear. [13] [14] [15] Classification has been revised along genetic lines. [5] There are two morphological forms of Ursus arctos: the grizzly and the coastal brown bears, but these morphological forms do not have distinct mtDNA lineages. [16]
