A resident napoleon wrasse patrols Bay Canh Wall's deeper sections, the pronounced green hump on its forehead and thick lips identifying this individual as a large male who has held this territory for multiple documented seasons. These fish are among the few predators capable of eating crown-of-thorns starfish — a significant service during outbreak periods when the starfish decimates coral coverage across Indo-Pacific reefs. Their vulnerability to fishing and slow growth to sexual maturity means every protected individual in Con Dao National Park represents a critical contribution to regional population stability.

How is this calculated?

Sighting evidence is compiled from iNaturalist observation records within a set proximity radius, filtered for quality-grade observations. “Last confirmed” is the date of the most recent research-grade record.
