The Guide · Protection

Protected on paper, and what that is worth

Manta rays have been fully protected across Indonesian waters since 2014, and the reef manta is listed Vulnerable by the IUCN. Here is what each layer actually covers — and what it does not.

Book with a briefed operator

In short

Capture and trade are banned nationwide under Ministerial Decree No. 4/KEPMEN-KP/2014. Komodo National Park bans collecting protected species in every zone. CITES Appendix II governs anything crossing a border.

  • Full national protection since 2014
  • Reef manta listed Vulnerable on the IUCN Red List
  • No statutory distance figure exists in Indonesia

Four layers, and what each one does

Named so you can check them yourself rather than take our word for it.

The 2014 decree covers roughly 6 million km² of national waters — at the time, the largest manta sanctuary in the world. IUCN reassesses periodically, so check the live entry if you need it for research or policy.

In practice

What actually keeps them here

Law sets the floor. Whether mantas keep returning to these cleaning stations is decided in the water.

A live manta earns more

Manta tourism creates a direct economic reason to keep them alive. Entry fees fund the park; guides and crews depend on animals that come back.

Citizen science works

Every manta has a unique belly spot pattern. A clean underside photo goes into research catalogues and helps track individuals over years.

Site fidelity is the point

Undisturbed mantas return to the same coral heads. Crowded ones stop. Behaviour at the station is what decides whether the station keeps working.

Komodo National Park from the air

Local communities decide

Enforcement across six million square kilometres is not done by patrol boats. It is done by the people whose livelihoods depend on the animals staying.

The three-metre rule is not a law

Hold at least three metres, measured horizontally. Never overhead, never head-on. That is the figure this site publishes and the only one it publishes.

We are straight about where it comes from. Indonesia publishes no manta-specific national minimum distance for snorkellers or for vessels. Three metres is the park-and-operator standard applied here, not a statutory number, and we would rather say so than imply a law that does not exist.

The reason it holds anyway is behavioural, not legal. A manta that keeps being crowded off a cleaning station eventually stops using it.

What is asked of you

Every reputable operator briefs this before entry. None of it is optional.

Freediver at distance from a manta

Three metres, horizontally

Never above the animal, never in its path. Do not chase one that is moving away from you.

Snorkeller keeping clear of the reef

Nothing touches anything

No touching the animals, no hands or fins near a cleaning station where a manta is stationary and vulnerable.

Diver photographing a reef

No close-range flash

Ambient light only near the animals. The site is shallow enough that you do not need a strobe anyway.

Be sceptical of long-term trend claims in either direction. Operator observation is not a survey, and a good season is not a recovery.

Questions about protection

Book someone who briefs properly

The single biggest thing you control is which operator you hand your money to. Ask Komodo Luxury how they brief conduct before entry.
