The largest of the whales is the blue whale! The blue whale is currently the largest animal on the earth. An adult blue whale can grow to more than twice the weight of the largest dinosaur that ever lived on the earth, the Gibosaurus, and the weight of the African bull elephant.
About 30 times.
Blue whales are real sea monsters, with an average length of about 26 meters, a maximum record of 33.5 meters, and an average weight of 150 tons.
Such a giant beast needs a lot of food. An adult blue whale consumes about 1 million calories a day, which is equivalent to 1 ton of krill. Krill is its bulk food.
Blue whales swim into the shallows and swallow mouthfuls of water and krill.
The krill are filtered out by the tongue, which acts as a piston and forces water out through baleen, a large sieve-like structure suspended on either side of the upper jaw.
A blue whale's tongue is more than 3 meters thick and weighs more than an elephant.
