Ballooning Whale

The Blue whale (Balaenoptera musculus) is able to stretch its mouth cavity along specially designed groves on its throat to take in its own weight in water, so a 90 ton whale could take in 90 tons of water! Once a Blue whale has filled up they will filter the water for krill (a small shrimp-like crustacean), then let the water out and mow down on some tasty krill, 6-7 tons a day to be exact!
