Coral reefs are the one of earths most complex ecosystems, containing over 800 species of corals and one million animal and plant species. Here we see a Giant Clam (Tridacna gigas). These clams are a rare site due to overfishing for their meat and pearls they are a ‘Vulnerable species’.  Their shells are open by day to allow sunlight to feed the algae within via photosynthesis.
