Which is the largest animal in the world?

 

The largest animal in the world is the blue whale (Balaenoptera musculus). Blue whales are massive marine mammals and hold the distinction of being the largest animals ever known to have existed on Earth. They can reach lengths of up to about 100 feet (30 meters) and weigh as much as 200 tons or more.

These incredible creatures primarily feed on small shrimp-like animals called krill, filtering them through baleen plates in their mouths. Blue whales can be found in oceans around the world, and their sheer size and impressive presence make them a wonder of the natural world.
