Sea stars, Sea urchins, Sea cucumbers
During my firsts visits I never saw the basket stars. But now I see them a lot. Curled up in the sea rods. Only at night they open their arms. They hate light. As soon as I turn my light on one, it curls up. Makes it hard to get a picture. Shining the light just beside it (or have your buddy do that), get the camera ready and snap a shot!
