Description:
Humuhumunukunukuapu'a, our Hawaiian State Fish. AKA the Reef Triggerfish, spotted on a crystal clear day at Hanauma Bay, Oahu, Hawaii. The red he is flashing on the pectoral fin is a warning sign. When aggravated further he will extend the "trigger" on the top of his head (also red) for which these fish get their names.
