Long and slender, the blue whale's body can be various shades of bluish-gray dorsally and somewhat lighter underneath.[6] There are at least three distinct subspecies: B. m. musculus of the North Atlantic and North Pacific, B. m. intermedia of the Southern Ocean and B. m. brevicauda (also known as the pygmy blue whale) found in the Indian Ocean and South Pacific Ocean. B. m. indica, found in the Indian Ocean, may be another subspecies. As with other baleen whales, its diet consists almost exclusively of small crustaceans known as krill.[7]

Blue whales were abundant in nearly all the oceans on Earth until the beginning of the twentieth century. For over a century, they were hunted almost to extinction by whaling until protected by the international community in 1966. A 2002 report estimated there were 5,000 to 12,000 blue whales worldwide,[3] in at least five populations. The IUCN estimates that there are probably between 10,000 and 25,000 blue whales worldwide today.[1] Before whaling, the largest population was in the Antarctic, numbering approximately 239,000 (range 202,000 to 311,000).[8] There remain only much smaller (around 2,000) concentrations in each of the eastern North Pacific, Antarctic, and Indian Ocean populations. There are two more groups in the North Atlantic, and at least two in the Southern Hemisphere. The Eastern North Pacific blue whale population had rebounded by 2014 to nearly its pre-hunting population.[9
