Common clownfish (Amphiprion ocellaris). The Clownfish are a subfamily of the family Pomacentridae, native to the Pacific Ocean. Clownfish are marked by their behavior of living in a comensual relationship with sea anemones. A school of clownfish is always built into a hierarchy with a female fish at the top. When she dies, the most dominant male changes sex and takes her place. Photo credit: Jan Derk |
