Clownfish are native to wide ranges of the warm waters of the Pacific. Clownfish live in a mutual relationship with sea anemones, or in some case settle in some varieties of soft corals, or large polyp stony corals. Once an anemone or coral has been adopted, the clownfish will defend it vigorously. The anemone is required in nature because reef life is dangerous for small, brightly colored fish with very poor swimming abilities. For this reason, clownfish never stray far from their host. In an aquarium, where they don't have to forage for food, it is very common for clownfish to remain within six to twelve inches of their host for an entire lifetime. This series of "Marine Life Protection" proof one dollar coins has been a hit with collectors since the first coin was issued in 1992. It is hard to say whether the obverse or reverse is the most attractive, but they are becoming exceedingly hard to find. Palau was chosen as the location for the 10th season of the hit reality series Survivor, and this coin depicts regional marine life, as well as a beautiful mermaid. This One Dollar coin is legal tender and has been issued by authority of the government of Palau.
