Sgt. Pepper, born on June 8, 2008 at The Mirage, one of six dolphins at Siegfried & Roy’s Secret Garden and Dolphin Habitat in Las Vegas died on June 4 from complications arising from a lung affection. The dolphin is the 14th to die at the educational attraction since it opened at The Mirage in 1990.
Animal welfare advocates have long voiced their concerns that dolphins are not suited for such public displays, and that the exhibit’s confines are inadequate when compared to the natural habitat of the ocean.
