Walt Conti, founder and CEO of Edge Innovations, uses a handheld controller to move an animatronic dolphin in a tank at the company's warehouse in Fremont, California, U.S., September 30, 2020. Darting around the pool as a group of swimmers stands in the shallow end, the dolphin looks much like those that jump through hoops and perform acrobatics at theme parks. REUTERS/Nathan Frandino
