We Watched “Grizzly Man” With a Bear Biologist. It Got Weird. - Backpacker

When you're eaten by a bear, they're very different from other predators, in that a lion or a tiger or a big cat is going to dispatch their prey and bite through the windpipe or do something to kill it, so they can then drag it somewhere to consume it safely. A bear doesn't do that; a bear will literally sit on you and eat you. Often these people die by bleeding out, and it takes a long time. It's 10 to 15 minutes of this bear sitting on you eating you alive, not ripping out necessary organs or something to kill you. Sometimes you luck out, and the bear kills you quickly. In his case, that wasn't what happened.
