I love it when a wild sea creature chooses to interact with me. Mammals are the most likely to show an interest in me, but sometimes Rays do as well.
This morning two Manta Rays swam by underneath me before one of them swam up toward me. It showed its underside and swam around me three times, close enough to touch. Yes, I was nervous, but also thrilled.
It didn't seem to mind me swimming along with it for the next half hour and even came back up for another dance.
