Balaenoptera musculus

The blue whale is the largest animal that has ever lived on Earth. Its size is certainly impressive, but this does not make it invincible. For several years now, the blue whale has been on Canada’s list of threatened species, and the Atlantic population is currently listed as endangered. It lives in cold waters and has long been a favourite target for Atlantic whalers, which has greatly contributed to the species’ decline. Blue whales are easily recognized due to its imposing size, long body, prominent head, and particularly, the 9-metre spout of water from its blowhole!
