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.lue 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 whalers until protected by the international community in 1966.
Blue whales are rorqual whales, whales that have pleated throat grooves that allow their throat to expand during the huge intake of water during filter feeding. Blue whales have 50-70 throat grooves that run from the throat to mid-body. SIZE Blue whales grow to be about 80 feet (25 m) long on average, weighing about 120 tons (109 tonnes). The largest specimen found was a female 94 feet (29 m) long weighing more 174 tons (158 tonnes). The females are larger than males, as with all baleen whales.
