5 Polar Bear
Compared with other bears, the polar bear has a smaller head, a longer neck and a much more imposing stature. Although the average male polar bear weighs somewhere between 600 and 1,200 pounds, some of the largest stand up to 10 feet tall on their hind legs and weigh more than 1,700 pounds. Females are considerably smaller, weighing 400 to 700 pounds. Polar bears feed primarily on ringed seals, but they’re also happy to eat whales, walruses, small mammals, birds’ eggs and plants.
4 American Crocodile
Although most of North America’s largest carnivores live in cold climates, the American crocodile, which can weigh up to 2,000 pounds, lives in warmer areas. A small population inhabits south Florida, but the largest American crocodiles live in Central and South America, where males reach lengths of up to 20 feet. They lounge around lakes and wetlands, eating small mammals, birds, fish, frogs and insects, living as long as 70 years in the wild.
3 Steller Sea Lion
Weighing about 2,200 pounds on the average and stretching up to 9 feet long, this enormous sea lion deserves to be called stellar. The steller sea lion, which resides along the west coast of North America, scarfs down octopus, squid, fish and sometimes small seals. Although female steller sea lions are smaller than males, females enjoy longer lives, living up to 30 years, while males live about 18. A group of stellers is called a raft when they’re in water and a colony when they’re on land.
A walrus is sheer girth. Far outweighing land mammals of the continent, the average male walrus weighs more than 3,000 pounds, while a female weighs nearly 2,000. Although it spends most of its time on land, it frequently scavenges the nearby water for its meals. As a walrus swims, the long whiskers on each side of its face help it detect food along the ocean floor. This creature must eat a lot of shellfish and clams throughout its 40-year lifespan.
1 Blue Whale
The blue whale isn’t just the largest carnivore on Earth–it’s the largest animal that ever existed on this planet. It’s bigger than any dinosaur that ever graced this land. Blue whales live in live in all the world’s oceans and weigh up to 200 tons. One of these guys weighs more than 40 elephants.
