Whale sharks visit Fahal Island's upwelling-rich waters primarily October through March, drawn by concentrations of fish eggs and zooplankton generated by cool, nutrient-rich currents from the Arabian Sea. As the ocean's largest fish they filter thousands of litres of water hourly but remain entirely harmless to divers. Satellite tagging studies suggest individuals in Oman undertake transoceanic migrations connecting the Arabian Sea to the western Indian Ocean.

Whale Shark 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.
