A Manta Ray did repeated back-flips for my entertainment this morning - well, also to make the most of an abundant food source.
I also got to see my very first-ever Spanish Dancer, a nudibranch whose gyrations as it moves through the water resemble those of a long-skirted dancer.
Oh, and eleven Spinner Dolphins made a single pass up to, and then by me as well.
Not a bad swim adventure.
