Eagle rays pass through Les Mamelles in aggregations during cooler upwelling months, riding the thermocline boundary between cold deep Atlantic water and the warm surface layer. They feed on buried mollusks and crustaceans in the sandy plateaus adjacent to the reef, leaving characteristic excavation pits in the substrate. Their wingspan can exceed 3 m and they often travel in loose squadrons of 5 to 20 individuals.

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.
