Manta rays: cleaning stations and feeding frenzies

Manta rays: cleaning stations and feeding frenzies

There are two species of manta ray. Reef mantas (Mobula alfredi) have wingspans up to 5 meters and are the ones you'll see at cleaning stations. Oceanic mantas (Mobula birostris) can reach 7 meters and are more pelagic and harder to find.

Both are plankton feeders, harmless to humans, and extraordinarily curious. Manta encounters are among the few in scuba where the animal often initiates the interaction.

Where mantas go predictably

Mantas visit cleaning stations — specific rocks or bommies where small wrasse and butterflyfish live. They hover over the cleaner fish for 5–30 minutes while parasites are removed, then leave. Divers who know the station schedule can arrive at dawn and wait.

Notable stations:

• Manta Point, Komodo (Indonesia) — reef mantas year-round, oceanics in August–October
• Manta Sandy, Raja Ampat — reef mantas almost guaranteed
• German Channel, Palau — reef mantas in the green season
• Revillagigedo (Socorro), Mexico — oceanic mantas, the best interactive encounters in the world

Feeding frenzies

When the plankton is thick, mantas forget the cleaning station entirely and go into feeding mode. Hanifaru Bay (Maldives) is the global capital of manta feeding — 100+ animals at once, barrel-rolling through bait balls. Snorkel-only, strictly permit-controlled.
