A Mystic Aquarium trainer rubs the tongue of a Beluga whale as a gesture of affection, Friday, May 14, 2021, in Mystic, Conn. Three Beluga whales will arrive at the aquarium later Friday from Marineland in Niagara Falls, Ontario, Canada. The whales will be leaving an overcrowded habitat with about 50 other whales and will be at the center of important research designed to benefit Belugas in the wild. (AP Photo/Jessica Hill)
