Four more beluga whales swam into their new home at Chicago's Shedd Aquarium on Thursday after an "intricate rescue" from the shuttered Marineland of Canada. Shedd welcomed 27-year-old Caspian, 23-year-old Peekachu, 22-year-old Secord, and 20-year-old Rain into its 3-million-gallon Abbott Oceanarium where they can settle in while out-of-view of aquarium visitors. #sheddaquarium #belugawhales #rescue
