In Real Life
With a length of 100ft and a weight of around 200 tons, the blue whale is the largest animal to have ever existed, outsizing even the dinosaurs. Even baby whales, called calves, are born at 25ft long and weigh 3 tons. An adult blue whale's heart is the same size as a car, and its beats can be heard from up to two miles away.
Their unbeatable size means they also rank as the third loudest animal on the planet. They can vocalise songs in order to talk to other whales, such as when looking for a mate. These vocalisations can hit 188dB in volume (louder than a jet engine, rock concert, or 12-gauge shotgun blast), and can travel for hundreds of miles through the water. The only animals that beat it for volume are sperm whales (230dB) and pistol shrimps (200dB).
Despite their gargantuan size, the blue whale's primary diet is krill. While krill typically grow to a size of a few inches, the blue whale can make a meal of them by attacking patches of them. Due to how much energy is expended when eating large patches of krill, blue whales have to be picky with which patches to attack.
Once they find a suitably sized ball of krill, they'll lunge forward with mouth open to scoop up as much as possible. This catches the krill, but also causes their mouths to fill with seawater, which is undesirable. The blue whale solves this problem by forcing the water back out of its mouth through the baleen plates, a fingernail-like material that lines the upper jaw. The baleen plates allow water to pass out of the mouth, but catches all the krill trying to pass through, filtering the food from the water. A blue whale will need approximately 2,000lbs of krill to feel full.
