Officially the deadliest animal in the states since 1970, the brown bear has been responsible for 70 deaths in the last 50 years and their population is widespread throughout the continent. Captive bear attacks do happen, but most of America’s attacks are done by wild bears and national parks like Yellowstone are hotbeds for such incidents. Brown bears are large species, often known as grizzly bears in North America. Their subspecies, the Kodiak bear, which inhabits the islands of the same name in Alaska, is the largest known species of bear in the world, but most brown bears grow to around seven feet and weigh up to 1,000 lbs.
