Epulopiscium
Epulopiscium fishelsoni - a visible species of microbes"Epulopiscium fishelsoni was first found in the gut of the brown surgeonfish Acanthurus nigrofuscus in the Red Sea in 1985. Since then, similar organisms have been found in surgeonfish in the Hawaiian Islands, French Polynesia, Tuvalu, Guam, southern Japan, Papua New Guinea, the Great Barrier Reef, and South Africa (Bresler et al. 1998). Due to the daily cycle of the E. fishelsoni, it affects the pH of the surgeonfish's gut fluids differently during the day and night which suggests that cyclic metabolic changes occur within the bacterium."
