Even more compelling is the history behind the exhibit. Chris Porter, one of the creators of Ocean Walls, is no stranger to cetaceans and our oceans. He got his start as a trainer at Sealand of the Pacific where he worked with Tilikum, the whale highlighted in the film Blackfish. Later he became senior trainer at Vancouver Aquarium. Following his work at Vancouver Aquarium, he was one of the leading dolphin traders in the captivity industry, capturing dolphins in the Solomon Islands. In 2009, Chris came under fire for his work in the trade and left the Solomon Islands, leaving behind the dolphin export business as well.
