The hotel where I was staying was right on the beach. One of the enterprising young men there knew the wildlife in the sea, and led us for an hour, walking no more than calf-deep in the sea, showing us the various creatures.
Other than the sea snake, and "some kind of starfish", I have no idea what most of these are, so if you do then please leave a comment and I'll add it to the image's description.
