Top 12 Heaviest Animals in the World

12. Kodiak Bear

The Kodiak bear is ranked 10th on the list. This is an animal that lives on Kodiak Island, an archipelago in Alaska. A male Kodiak bear has an average height of up to 3 meters and weighs about 680 to 816 kg. Compared to males, female Kodiak bears are usually about 20 – 30% smaller.

Kodiak bears are much heavier than other species in the same bear family due to the diversity in food consumption of this animal. To “hibernate” in the spring, they will eat leaves, causing their body weight to increase by about 50 kg. % at this time. Being isolated alone on this island makes them unable to hunt other animals and unable to help their friends of different species.
