The Blue whale (Balaenoptera musculus) is the greatest mammal on Earth. There are three main subspecies of the Blue Whale: musculus of the North Atlantic and North Pacific, intermedia of the Southern Ocean and brevicauda found in the Indian Ocean and South Pacific Ocean. Even though it hunts very deep in the ocean, it has to come at the surface from time to time to take air. The air is exhaled with big pressure and the water jet that is formed can reach 6 meters height. Below you can find a pictures gallery with the great Blue Whale.
