There was once a time when aquariums around the world consisted of a tank with vertical transparent walls through which people viewed the fish from the outside. This changed in 1985 when Kelly Tarlton’s Underwater World opened to the public in Auckland, New Zealand. This aquarium featured a revolutionary design where the tank contained a transparent viewing tunnel running through the middle, so the visitors felt they entered the tank and were surrounded by the sea creatures. This aquarium design, which now has been copied throughout the world, was conceived by New Zealand marine archeologist and diver Kelly Tarlton. Tarlton’s new aquarium design proved very popular, and within 7 weeks, the museum had 100,000 visitors. Unfortunately, Tarlton died of a heart condition at the untimely age of 47, but his museum, now renamed “SEA LIFE Kelly Tarlton's Aquarium” still lives on. The video below was shot inside an aquarium tunnel in Ripley’s Aquarium of The Smokies in Gatlinburg, Tennessee.
