Even a small black bear cub can climb very high and fast [their only defence] .Their very curved ,90 * , shows that ! Holding one requires two people , one to hold the bear and one to unhooks those claws from your clothing ! We checked out a family with the Game officials.
Take a look at the brown bears almost straight claws and a hump over the shoulders [muscle !] for digging .Here ground squirrels are a favorite food and bears will dig up a mountain to get one !
Polar bears ?I used to have photos of some bears trying to eat one of our surfaced submarines thinking it was a whale !!!
