Stingray Exhibit Remains Closed at Brookfield Zoo

More on the stingray incident at Brookfield Zoo: the "Sharks at Stingray Bay" exhibit remains closed after temperature controls on a 16,000 gallon saltwater tank skizzed out on Monday morning. Sixteen stingrays died as a result of water temperatures rising to almost 90 degrees - 10 degree above normal. A San Diego-based company called Living Exhibits created and manages the temporary exhibit at the zoo. Company president Mike Yeakle, Brookfield Zoo, and ComEd are all working together to investigate the cause of the malfunction. One possibility is that the tank overheated when a power supply fluctuation triggered the tank's heaters. Prior to the accident, the exhibit contained 33 stingrays, eight sharks, and three horseshoe crabs. [Trib, CBS2]
