Four more belugas have arrived at a Chicago aquarium as part of a plan to move Canada's last remaining captive whales from a shuttered theme park to aquariums in the United States and Spain.
The four whales, named Caspian, Peekachu, Rain and Secord, were the second group of belugas sent to Chicago's Shedd Aquarium from Marineland, in Ontario near Niagara Falls, after an initial four arrived in July.
