French Polynesia Sharks and Mantas: What the 2026 Survey Saw
Everyone comes to French Polynesia for the humpbacks. But when a research plane flew over the islands in 2026, the people on board also counted whale sharks, tiger sharks, hammerheads, oceanic whitetips and oceanic mantas. The supporting cast is enormous, and some of it has teeth.
So which sharks and rays did the survey see? The REMMOA II team reported at least four shark species during its flights across the archipelagos: whale sharks, tiger sharks, great hammerheads and oceanic whitetips. They also recorded oceanic manta rays.
And the plane was not only looking for sharks. The survey covered the surface waters around all five archipelagos, and it counted cetaceans, turtles, seabirds, marine debris and drifting fish-aggregating devices too. Think of it as a census of everything big enough to see from the air.
A whale shark sighting is not a whale shark season
Here is where it gets easy to get excited too fast. An aerial sighting tells us where an animal was observed, on one day, from one plane. It does not tell us that the animal is common at a particular island. It does not say it shows up every week, or that visitors can reliably find it.
This matters most with animals that travel far. A whale shark can be recorded in the region without French Polynesia becoming a predictable whale shark destination. The same is true for a tiger shark or an oceanic manta. A verified record is a lovely piece of science. It is not a booking guarantee, and we would never sell it as one.
Why survey the whole neighbourhood?
The project wants to understand where marine animals live, how many there are and how they use their habitat across French overseas waters. In 2026 the fieldwork covered more than 850,000 square kilometres. Researchers are now working through the data. They are also comparing it with the earlier baseline, collected roughly 15 years before.
A survey that looks at the wider ocean can show much more than a list of famous animals. It can point to areas where large marine life gathers, help track pressures like debris and fishing devices, and guide conservation decisions. The analysis may sharpen what we know about how wildlife uses the different island groups. For that, we have to be patient and wait for the results.
The best kind of wildlife checklist
I love sharks and rays. I also do not want to turn their existence into a promise that you will tick off each species on demand. For now, the honest story is simple: the 2026 campaign documented these animals in French Polynesia's waters, and the detailed results are still being worked on.
So if your dream is a manta, a whale shark or a hammerhead, ask a local expert what is really expected at your chosen site and season. Then leave a little space for the ocean to surprise you with something else. Our French Polynesia guide is where we gather the practical context around its wildlife.
Questions people ask
Which sharks did the REMMOA II team report?
The team reported at least four shark species: whale sharks, tiger sharks, great hammerheads and oceanic whitetips. Researchers also recorded oceanic manta rays.
Does a survey sighting mean I will see these animals?
No. Aerial sightings show where animals were observed. They do not show that an animal is common at an island, appears every week, or can be reliably seen by visitors.
How big was the 2026 survey?
The fieldwork covered more than 850,000 square kilometres. Researchers are now analysing the data and comparing it with an earlier baseline from roughly 15 years before.
Wildlife encounters are never guaranteed and never forced. Ocean Calling works only with vetted, ethical local operators, and every animal is free to approach, or not, entirely on its own terms.
