Cap Blanc's cave systems shelter an exceptional density of Mediterranean moray eels, which use the rock fissures as permanent territories from which they ambush fish and octopus. Large individuals over 1.2 m occupy the deeper cave sections, sometimes sharing overhangs with conger eels in a rare cohabitation. Their presence throughout the year makes moray encounters essentially guaranteed at this site.

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.
