(Scottsdale, AZ) -- Protestors are calling for Dolphinaris Arizona to release its remaining five dolphins after the one of its dolphins died on Sunday. The 11-year-old bottlenose was the third dolphin to die at the Scottsdale-area attraction in the past 16 months. The facility says Khloe had been suffering from a chronic illness for the past six years and that its other dolphins are doing well.
