Red Sea Fish
Why are reef fish so colorful, like butterflies? It is because the water in Red Sea is ever transparent. The fish see each other from far distance. Unlike a river, here in Red Sea fish body coloring does matter, like coloring does matter for field butterflies. That is why the evolution created coral butterfly-fish .
Underwater photos at this site are taken without a scuba. I used only a diving mask and a snorkel (a specially curved plastic respiratory tube). The photos were made by digital cameras - Nikon cp880, Fuji f30 .
