Angelfishes of the genus Pomacanthus are known for their dramatic colour changes with growth. The juvenile Emperor Angelfish is dark blue-black with a white ring on the rear of the body. This is surrounded by incomplete circles of blue and white. This species grows to about a foot in length. The Juvenile Emperor Angelfish can be found on coral reefs throughout much of the Indo-Central Pacific. In Australia it is found from the central Western Australian coast, around the tropical north and south to the central New South Wales coastline. This series of "Marine Life Protection" proof one dollar coins has been a hit with collectors since the first coin was issued in 1992.

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.
