The yellowmargin moray is identified by its mottled brown body and the distinctive yellow edging on its dorsal fin. It is among the most commonly encountered morays on Réunion reefs, occupying crevices on the boulder zone at Pointe des Aigrettes. Like all morays it is a nocturnal hunter, but at this site individuals are frequently seen with their heads extended during the day, waiting for small fish to pass within striking range.

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. Record count covers a rolling 24-month window. Confidence reflects record count, recency, and consistency of seasonal signal.
