🐾Beluga whale
Le Bélouga ou Béluga (Delphinapterus leucas), appelé également Marsouin blanc, Dauphin blanc ou Baleine blanche, est une espèce de cétacés de la famille des Monodontidae vivant dans l'océan Arctique et dans l'estuaire du Saint-Laurent. Il est le seul représentant actuel du genre Delphinapterus et constitue avec le Narval (Monodon monoceros) l'une des deux espèces de sa famille. Il dispose d'un des sonars les plus sophistiqués de tous les cétacés. Ce sonar lui est indispensable pour s'orienter et se repérer dans les canaux de glace immergés, qui forment un véritable labyrinthe.
