Common questions
Are manta rays dangerous?
No. Manta rays have no stinger — unlike stingrays, the barb is absent — no teeth used for defense, and they eat plankton. They pose no threat to divers. The etiquette matters in the other direction: never touch or chase one; contact can remove the mucus layer that protects their skin, and harassment drives them off cleaning stations.
How big is a giant manta ray?
The giant oceanic manta ray is the largest ray in the world: wingspans commonly reach 4–5 metres, with the biggest individuals around 7 metres. It is listed as Endangered on the IUCN Red List, which is why many encounter sites operate under strict approach rules.
Do manta rays sting like stingrays?
No. Mantas belong to the same broad group as stingrays but have lost the venomous tail barb entirely. A manta’s tail is harmless. The correct behavior around them is still hands-off: stay low and still near cleaning stations, let the animal control the distance, and it will often pass remarkably close on its own.
