The blue whale

The blue whale is a marine mammal and a baleen whale. Reaching a maximum confirmed length of 29.9 meters and weighing up to 199 tonnes, it is the largest animal known to have ever existed. The blue whale's long and slender body can be of various shades of greyish-blue dorsally and somewhat lighter underneath

The blue whale was driven to the brink of extinction by commercial whaling in the 1800s and early 1900s. This species was protected from commercial whaling by the International Convention for the Regulation of Whaling in 1966.
