I’ve seen this particular ray several times while snorkeling. I think it’s a young one, since it’s somewhat smaller than others I’ve seen. It glides over the coral with little effort, but sometimes shifts into high gear and shoots off with a good turn of speed. It’s not aggressive and doesn’t appear bothered by my presence, but since eagle rays have venomous spines near the base of the tail, I don’t get too close.
