When we think of bears, images of powerful, majestic creatures roaming the wild immediately come to mind. These formidable animals vary significantly in size and weight, depending on their species and habitat. Here, we explore the largest types of bears in the world, ranked from the biggest to the smallest on record.
1. Polar Bear (Ursus maritimus)
Habitat: Arctic regions across Canada, Alaska, Greenland, Norway, and Russia.
Size on Record: Males can weigh between 900 and 1,600 lbs, with the largest specimens reaching up to 1,700 lbs. Standing on their hind legs, they can tower up to 10 feet tall.
Notable Feature: Known for their thick, white fur and incredible swimming abilities, polar bears are the true giants of the bear world.
One of the largest recorded polar bears was an immense specimen killed near Kotzebue, Alaska, and displayed in a replica at Polet’s Store in Nome in 1960. According to the local paper The Nome Nugget, this bear measured an astonishing 10 feet, 11 inches, a true testament to the Arctic’s capacity to produce such massive apex predators. The capture of this giant bear reflects a time when hunting polar bears for sport was still common, and the harsh yet bountiful Alaskan environment allowed these bears to reach record-breaking sizes. Today, however, polar bear hunting is heavily regulated to preserve these giants for future generations.
2. Kodiak Bear (Ursus arctos middendorffi)
Habitat: Kodiak Archipelago in Alaska.
Size on Record: Males typically weigh up to 1,500 lbs, with some extraordinary specimens exceeding this and rivaling the size of polar bears.
Notable Feature: These bears are a subspecies of the brown bear but are distinguished by their isolated habitat on Kodiak Island, which has allowed them to grow to such impressive sizes.
3. Kamchatka Brown Bear (Ursus arctos beringianus)
Habitat: Kamchatka Peninsula in eastern Russia.
Size on Record: Males can reach weights of up to 1,500 lbs, making them among the largest brown bear subspecies.
Notable Feature: These bears thrive in the remote, wild landscape of Kamchatka, which is rich in salmon and other food sources that contribute to their massive size.
4. Grizzly Bear (Ursus arctos horribilis)
Habitat: North America, primarily in Alaska, western Canada, and parts of the northwestern United States.
Size on Record: Average weights range up to 800 lbs, with some recorded specimens reaching over 1,000 lbs.
Notable Feature: Known for their iconic hump and ferocious nature, grizzlies are a symbol of raw wilderness.
5. Eurasian Brown Bear (Ursus arctos arctos)
Habitat: Europe and Asia, spanning from Scandinavia to the forests of Siberia.
Size on Record: These bears can weigh up to 800 lbs, though most fall below this threshold.
Notable Feature: Their size and coloring vary greatly depending on the region they inhabit.
6. American Black Bear (Ursus americanus)
Habitat: North America, found in forests, mountains, and swamps across the continent.
Size on Record: Though most weigh between 200 and 600 lbs, some large males in specific regions can exceed 600 lbs.
Notable Feature: Known for their adaptability and diverse coat colors, including black, brown, and even cinnamon.
7. Asiatic Black Bear (Ursus thibetanus)
Habitat: Asia, including countries like China, Japan, and parts of the Himalayas.
Size on Record: Typically weighs between 200 and 400 lbs, with some larger males over 400 lbs.
Notable Feature: Also known as the “moon bear” due to the crescent-shaped patch on its chest.
8. Spectacled Bear (Tremarctos ornatus)
Habitat: South American regions, primarily the Andes Mountains.
Size on Record: Males can weigh between 220 and 400 lbs.
Notable Feature: The only bear species native to South America, known for the distinctive markings around their eyes that resemble glasses.
9. Sloth Bear (Melursus ursinus)
Habitat: India and Sri Lanka, often found in grasslands and tropical forests.
Size on Record: Weighs between 200 and 300 lbs, with some reaching up to 400 lbs.
Notable Feature: Characterized by their shaggy fur and long snouts, these bears are expert termite and ant hunters.
10. Sun Bear (Helarctos malayanus)
Habitat: Southeast Asia, including Malaysia, Indonesia, and Thailand.
Size on Record: The smallest bear species, weighing between 60 and 150 lbs.
Notable Feature: Known for their short fur and long tongues, which help them extract honey from beehives.
