Oceanic manta rays visit Mona's cleaning stations during the warmer summer months, riding the productive currents of the Mona Passage. Their wingspans regularly exceed 4 m, and encounters at the reef edge at dusk are among the most memorable in the Caribbean.

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.
