Fungia feeding. Fungia are large individual corals that don't form colonies or reefs. Their large and very expandable mouths allow them to eat large pieces of food compared to most corals. The movie was captured with epifluorescence, using the Fungia's own natural auto-fluorescence stimulated by UV, blue and green excitation light.
