This was the biggest living Cowrie that I have ever seen. After examination it was carefully placed back where it was found.
We were also greeted by a big Manta Ray and, as we approached shore, by a huge school of small fish being chased by a much larger predator fish. Due to poor visibility, and how fast the fish were moving, we weren't even sure what we were seeing at first. Thank goodness the camera was able to clarify matters a bit.
We were happy campers and really glad we went for an ocean swim today.
