Brown bears have long, intimidating claws. However, since they are not retractable, they are relatively blunt and are usually used for digging. These bears are incredibly strong, able to break the necks of many large prey with one powerful blow. Their thick fur and layer of fat help to insulate them against the extreme cold temperatures of their habitat.
