The biggest animal known to have ever existed, at up to 30 metres in length and with a maximum recorded weight of 173 tonnes and probably reaching over 181 tonnes, the Blue Whale is one of the baleen group, like the Right Whale.
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 whalers until protected by the international community in 1966. A 2002 report estimated there were 5,000 to 12,000 blue whales worldwide.
