A resident napoleon wrasse patrols the sanctuary wall, its distinctive fleshy hump and thick lips making it unmistakable among Apo Island's reef residents. It feeds on hard-shelled invertebrates including sea urchins, mollusks, and crustaceans that few other predators can handle, occupying a unique predatory niche on the reef. Napoleon wrasse are protogynous hermaphrodites — all individuals are born female and some transition to male — and their slow maturation makes them especially vulnerable to fishing pressure, so the protected status here is critical.
