"We went on the 7:30 am swim and saw 38 sharks on our trip. I recommend buying the GoPro footage, as they got great shots of us swimming in the ocean with the sharks….One Ocean Diving does a tremendous job on conservation, education, and research. They do research on shark behavior and conducts population counts. The only thing that I would recommend they do is to publish their findings in a peer reviewed journal! Other than that, I only have positive things to say about this organization."

"Once we were in the water it was so surreal, like an out of body experience in a giant blue room! The sharks were beautiful and elegant watching them around us felt so relaxing I'd recommend for anyone and everyone to do this. "

One Ocean Diving’s goals

One Ocean Diving aims to redefine the relationship we have with sharks. The goal is to help people make judgments based off scientific fact instead of Hollywood movies. Sharks help maintain balance and are like the ocean’s immune system. Unfortunately they are decimated globally just for their fins. They use ecotourism to fund research on shark population trends.
