Great Star Coral (Montastrea cavernosa) – Grecian Rocks, John Pennekamp St Park, Fl Keys
Great Star Corals covered the caps of the reef structure, creating these eerie iridescent ‘mountain tops’. This picture shows how distinctly certain reef creatures and corals respond to our fluorescent lights (green glow) as the non-responsive areas faded to darkness.
