The Blue Whale (Balaenoptera musculus) is the largest animal known ever to inhabit our planet. The Blue whale can be seen, in the estuary of the Saint-Lawrence river and along the Gaspesian peninsula and occasionally in the Mingan area in summer and fall. Some individuals are sporadically seen in the St. Lawrence in winter.
