Welcome to a whole new underwater world, thanks to the work of a YouTube creator who calls himself the Fish Whisperer (real name: Kyle Naegeli), the cooperation of a red-eared slider turtle at a local pond and a GoPro video camera. Naegeli is something of a marine YouTube star — he has over half a million subscribers to his channel, and has been sharing his videos of fishing adventures and encounters with freshwater sea creatures going back six years.
