Poilão hosts the largest green turtle nesting colony in West Africa, with population surveys recording thousands of nesting females during peak season from October to February. In the water, turtles are encountered at virtually every dive, either resting on coral heads, feeding on algae, or swimming purposefully between cleaning stations where wrasse remove barnacles and parasites from their shells. The density of turtles here reflects both the island's formal protected status and the extraordinarily low human footprint across the archipelago.

Green Sea Turtle is listed as a curated species here based on historical reports.

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.
