Blue whales are the largest animals ever to live on our planet. They feed almost exclusively on krill, straining huge volumes of ocean water through their baleen plates (which hang from the roof of the mouth and work like a sieve). Some of the biggest individuals may eat up to 6 tons of krill a day. Blue whales are found in all oceans except the Arctic Ocean. There are five currently recognized subspecies of blue whales.
