The humphead wrasse (Cheilinus undulatus) is a wrasse that is mainly found in coral reefs in the Indo-Pacific region. It is also known as the Māori wrasse, Napoleon wrasse, Napoleonfish; or "So Mei" 蘇眉 (Cantonese), "Mameng" (Filipino), and "Merer" in the Pohnpeian language of the Caroline Islands.

Thanks to Rene Keultjes for helping me determine the name of this unusual-looking creature.
