At night the Goniopora corals are transformed as they fluoresce,red,green and orange under blue light. The mouths of the coral animal,the polyp,are orange and the bodies and tentacles are red,tipped with fluorescent green. Some scientists believe that the fantastic colours of the pigments form a kind of sunscreen from the string ultraviolet rays in shallow water. Tondoba Bay,Marsa Alam,Red Sea,Egypt | |
