“There’s another one!” I heard someone on the beach exclaim, as I stuck my snorkelled head back into the water, searching now for not two, but three stingrays that had been spotted just offshore. Sure enough, there it was, another ray gracefully skimming the ocean floor just meters away from a fishing boat anchored in water that was barely chest-deep. Following it through my underwater camera’s display as Henk and I swam behind it, I couldn’t believe that I had seen a trio of these underwater creatures for the first time, mere meters offshore from the Grand Oasis Tulum resort where we were staying. Despite the resort’s tagline as ‘an oasis of calm’, I was about as excited as a novice snorkeller could get!
