Caption
Acoel flatworms (Waminoa sp) on polyps of Bubble coral (Plerogyra sinuosa) Indonesia. This flatworm can cover the whole surface of some corals, leaving them no way to catch plankton and their symbiotic algae (Zooxanthelles) can't produce the necessary sugar. Those corals are slowly dying from starvation.
