The Largest PredatorThe Blue Whale. At up to 33.58 meters (110 ft 2 in) in length and 172 metric tons (190 short tons) or more in weight, it is the largest animal ever known to have existed. What makes the Blue Whale a predator is that, as with other baleen whales, its diet consists almost exclusively of small crustaceans known as krill. The whales always feed on large amounts of krill, sometimes eating up to 3,600 kilograms (7,900 lb) of krill in a single day. Though the whales sometimes take small numbers of copepods, a form of zooplankton, the majority of their diet consists of living organisms, making the Blue Whale the world's largest predator to date.
