The Shedd Aquarium on Friday morning released preliminary medical findings of the deaths of three beluga whales, two of which passed away after being transferred to Chicago from the shuttered Marineland Park in Niagara Falls, Ontario. The findings from the Shedd come from a post-mortem necropsy investigation into the deaths of rescued belugas Peekachu and Rain and longtime Shedd resident Beethoven. #sheddaquarium #beluga #marineland #whale
