Real-world information
The Napoleonfish, Cheilinus undulatus, is more commonly known as the humphead wrasse; both names are derived from the large hump on the forehead of adults. Males are larger than females. Due to overfishing and the destruction of coral reefs, their natural habitats, the fish is now considered endangered. Humphead wrasses are protogynous hermaphrodites: all fish are born female, but contain the genes for both sexes, and some fish change sex to male a year or two after sexual maturity.
