Blue whales eat some of the tiniest creatures to swim in the sea, shrimp-like critters called krill. At the high points of the feeding season, blue whales can eat upwards of four tons of krill in a day. They do so with huge gulps of water, which is then flushed out by their huge tongue and filtered through their overlapped baleen plates, which are attached to their upper jaws. The leftover krill, usually numbering int he thousands, are then swallowed.

A blue whale's tongue can weigh as much as an elephant.

A blue whale's heart is approximately the same size as a Volkswagen Beetle.

Water sprays from their blowholes and reaches heights of 30 feet.

The humongous whales are also among the loudest animals, and their songs can be heard up to 1,000 miles away by other members of their species. It doesn't hurt that they have excellent hearing, and likely use the sounds to help sonar-navigate. Their calls can reach 188 decibels, more than a typical jet engine which registers 140 decibels.

Unfortunately, ble whales were almost wiped out by commercial whaling. In the first half of the 20th century, whalers killed some 300,000+ individuals.
