The Largest Animal in the World Is the Blue Whale.

The largest animal on Earth is the Antarctic Blue Whale (Balaenoptera musculus ssp. Intermedia). These massive animals can weigh up to 400,000 pounds and measure up to 98 ft. in length! An Antarctic Blue Whale’s heart is the size of a small car and during the main feeding season, just one of these creatures consumes around 7,936 lbs. of krill each day.
