How to spot the Reef manta ray when scuba diving
Manta alfredi
Found throughout tropical, subtropical, and temperate waters globally. Giant Mantas (Mobula birostris) are more oceanic, while Reef Mantas (Mobula alfredi) are more coastal, often associated with specific reefs or island groups.
Highly dependent on location, often tied to plankton abundance (feeding) or specific times at cleaning stations. Examples: Rainy season (Nov-Apr) in Komodo, specific monsoon seasons in the Maldives (e.g., Hanifaru Bay feeding frenzy May-Nov, peaking July-Oct), year-round potential in places like Socorro or Hawaii but with seasonal peaks.
Warm waters, typically 20°C to 30°C (68°F to 86°F).
Look for known cleaning stations (coral bommies/outcrops where mantas queue for cleaning) or areas with strong currents that concentrate plankton (channel mouths, specific bays like Hanifaru). Both reef and oceanic mantas can be encountered.
