1. Asiatic Black Bear
Asian bears, also known as “moon bears” or “white-chested bears,” are native to Asia and live in many countries, including the Himalayas, Iran, India, Korea, China, Russia, Japan, and Taiwan. They have black fur, a light brown muzzle, and a distinctive white patch on their chest. These bears can easily reach between five and six feet and weigh over 440 pounds, slightly larger than the African lion. Asiatic black bears are shy and live solitary lives. They are known for being aggressive towards humans, more than other bear species. Mature cubs and females with young nearby are more likely to attack, and people fear them due to their hostile nature. But in the wild, these bears mainly prey on small mammals, fish, and insects. Siberian tigers and brown bears are their only natural predators (besides humans). But wolves may prey on their cubs given the opportunity.
2. Green Anaconda
The green anaconda is one of the heaviest and longest snakes in the world. This boa species is a nonvenomous constrictor native to tropical rainforests in South America, although some have traveled as far north as the Florida Everglades. Green anacondas are olive green with black splotches across their bodies. They feature a narrow head with loosely-connected jaw bones that allow them to swallow prey much larger than themselves. Green anacondas can grow up to 30 feet long and weigh more than 550 pounds. It’s hard to believe that a snake can be bigger than a lion and a bear!
3. American Black Bear
Black bears are endemic to North America and, shockingly, considered one of the smallest bears on the continent. The American black bear, closely related to the Asian black bear, lives in forested habitats, occasionally making its way into human territories for food. Despite its name, this bear can be brown or even blonde in some cases. On average, American black bears grow between five and six feet and weigh over 500 pounds. The largest black bear on record weighed over 900 pounds and was nearly eight feet long. Black bears are less aggressive and more tolerant of people than other bears. They tend to live near human habitations but stay out of the way. Attacks are extremely rare and only occur when humans get too close to them or their cubs. While these bears are enormous, they still have several predators, including mountain lions, wolves, coyotes, grizzly bears, and other black bears.
4. Siberian Tiger
The Siberian tiger, also known as the Amur tiger, is a subspecies of the Mainland Asia tiger and is native to Eastern Russia and Northeast China. This tiger can withstand high latitudes, harsh climates, and long winters, primarily inhabiting Russian birch forests. It is rusty-red or yellowish, with black transverse stripes. Male Siberian tigers can weigh close to 700 pounds and reach 10 feet long. The largest Siberian tiger weighed over 900 pounds and measured almost 11 feet. Tigers, especially ones this giant, may seem like a serious threat, but they are pretty elusive and choose to avoid humans at all costs. Males can be territorial and defend themselves against poachers and those who get too close. Humans are their main predators. But this species is relatively docile compared to other tigers, like the Sumatrans tigers.
5. Kodiak Bear
Kodiak bears, also known as Kodiak grizzly bears or Alaskan brown bears, are the largest subspecies of the brown bear and the second largest living bear on earth. They are native to Southwest Alaska and strictly inhabit the islands in the Kodiak Archipelago off Alaska’s South Coast. They are entirely isolated from other bears on these islands and have been since the last ice age. Their coloration ranges from blonde to orange to dark brown. Male Kodiak bears can reach over ten feet tall and weigh up to 1500 pounds. The largest Kodiak bear in existence weighed over 1600 pounds. Only one person has died from a Kodiak bear attack in the last 75 years. Attacks from this species are rare; people have lived near them for centuries without much issue. However, they defend their territory when threatened and can be very aggressive. Due to their unique and isolated environment, Kodiak bears have no natural predators.
6. Polar Bear
Polar bears are the largest bears and land predators on earth. They are native to the Arctic Circle and live mainly on the sea ice in the Arctic Ocean. Their dependence on the sea and the seals that live within it classifies them as marine mammals. The polar bear topples heights of 10 feet and weighs over 1,540 pounds. The largest polar bear on earth was over 11 feet tall and weighed 2,200 pounds! Polar bears are incredibly aggressive, and they are known to hunt humans as prey when food is scarce. While they may not be inherently hostile, they are giant enough to see humans as weak, inferior food. They are fearless creatures, and rightfully so, as they have no natural predators.
