| Blue Whale |
Blue whales are the biggest creatures ever known to have existed on Earth. These eminent marine warm blooded creatures administer the seas at up to 100 feet (30 meters) in length and upwards of 200 tons (181 metric tons). Their tongues alone can weigh to the extent that an elephant. Their hearts, to the extent that an auto.
Blue whales achieve these brain boggling sizes on an eating regimen made about only out of little shrimp-like creatures called krill. Throughout sure times of the year, a solitary grown-up blue whale expends about 4 tons (3.6 metric tons) of krill a day.
