Which is the largest flesh eating animal in world?

It's not really accurate to call any animal a "flesh-eating animal" as if that's their primary diet. Many animals eat meat, but it's usually only part of their diet.

That said, the largest animal that primarily eats meat is the polar bear. Here's why:

* Size: Polar bears are the largest land predators on Earth, with males averaging around 660-1,500 pounds.

* Diet: While they occasionally eat berries and vegetation, their diet is almost entirely composed of seals, which they hunt by waiting near breathing holes in the ice or by ambushing them on land.

While some other animals like sharks, crocodiles, and whales are larger than polar bears, they don't primarily eat meat.
