The Blue Whale is the largest creature ever to have lived on earth. Their tongues alone can weigh as much as an elephant, and their hearts can weigh as much as a car!
Although the blue whale is a deep-water hunter, as a mammal it must come to the surface of the sea to breathe.
Although we can’t hear them, blue whales are one of the loudest animals on the planet. They communicate with each other using a series of low frequency pulses, groans, and moans.
