The world's largest ray visits the seamount to exploit cleaning stations on the summit and to feed on the dense zooplankton aggregations the upwelling produces. Individual mantas have been identified at this site repeatedly across multiple seasons via their unique ventral spot patterns. They are capable of descending beyond 1000 metres during the day and ascending to warm surface waters at night — behaviour documented by researchers using satellite tags in the Arabian Sea.

Oceanic Manta Ray 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.
