Head coral Favia favus under super macro
Location & date
Malapascua, Philippines: 17th November 2014
Favia favus is a reef building coral, found in shallow waters on the coral reef. This was taken during daytime and the polyps are retracted. The corallite on the left has something in its pharynx. The pharynx is the only opening. It is possible that the yellow object is a package of eggs and sperm. This is what is released by the corals in spawning events. The septae (rib like pattern) are clearly visible and form a pleasing pattern to the eye at this magnification.
About this image
Corals fascinate me as they are the building blocks of coral reefs which are the most biodiverse regions on the planet. The patterns formed by individual corallites are often very beautiful. By using a Super Macro converter, I was able to fill the frame with an individual corallite. I saw that this particular individual had something in its pharynx, which provides a focal point for the image.
