The Red Sea turtle-tracking study from Saudi Arabia’s NEOM Islands shows why protecting nesting beaches alone may leave important habitat uncovered. Researchers tracked 17 nesting turtles—11 hawksbills and six green turtles—and recorded movements to feeding grounds in both Saudi Arabia and Egypt. The results make a case for considering reefs, feeding areas, and the routes linking them to nesting sites in conservation planning, while remaining a small, specific study rather than a census of Red Sea turtles.
What did the NEOM Islands turtle study find?
The study tracked 17 nesting marine turtles from Shusha and Walah Islands, Saudi Arabia, over two nesting seasons. The sample included 11 hawksbill turtles and six green turtles. Researchers used platform terminal transmitters to map inter-nesting areas, migratory pathways, and feeding grounds. The indexed primary research record reports that foraging displacements ranged from 34.8 to 501.7 kilometers and identifies six feeding grounds: four in Saudi waters and two in Egyptian waters. The study record, published in Scientific Reports in 2025, is the source for those findings.

Some travelled hundreds of kilometers to feed, and the routes and destinations crossed national waters. The result makes habitat connectivity a practical conservation concern: a nesting site is one part of the habitat picture, not necessarily the whole picture.
The numbers need to be read at the scale the study supports. Seventeen tracked turtles over two seasons can show where those particular animals went; they cannot establish how every turtle from the NEOM Islands, or every turtle in the Red Sea, behaves. Nor does the reported travel range mean all turtles travel hundreds of kilometers. It is a range observed in this study’s tracked animals.

Why are nesting beaches not enough?
Because turtles also use places between nesting events and after leaving nesting areas. The study mapped inter-nesting habitat, migration pathways, and feeding grounds in addition to documenting movements away from the islands. Protecting a beach without considering these connected areas could leave important parts of the tracked turtles’ habitat outside the conservation picture.
A beach-focused approach can still matter: the study is about nesting turtles and begins with two Saudi islands where they nest. But the tracking evidence suggests that the relevant planning area may extend well beyond the shoreline. In this case, it includes habitats used between nesting events, routes across the Red Sea, and feeding locations in both Saudi and Egyptian waters.

This is a planning implication, not proof that any particular beach, reserve, or conservation program is inadequate. The study did not experimentally compare protection strategies or demonstrate that a specific intervention succeeded or failed. Its contribution is to show that tracking can reveal habitat use that a map of nesting beaches alone would not describe.
What role do reefs play in the findings?
The study record highlights broader inter-nesting habitat use by hawksbills, particularly reef systems. That matters because it draws attention to habitat used between nesting events, not just the beaches where eggs are laid. The record supports treating reefs as part of the habitat mosaic to consider; it does not establish that every hawksbill uses the same reefs or that all reef areas in the region are equally important.

The useful distinction is between a nesting location and the wider places an animal uses during its post-breeding movements. The study’s researchers mapped those different kinds of places, and the reported hawksbill reef association adds a reason not to define turtle conservation solely by the coastline. For planners, reef systems are an evidence-based consideration in this particular study—not a substitute for protecting nesting beaches or a claim that reef protection alone is sufficient.
How far did the turtles travel, and where did they feed?
Reported displacements to feeding grounds ranged from 34.8 to 501.7 kilometers. The researchers identified six feeding grounds: four in Saudi Arabia and two in Egypt. Those are the study’s reported endpoints and range; they should not be treated as a universal travel distance for sea turtles or as a complete map of feeding habitat across the Red Sea.

If animals use habitat in more than one country, a plan drawn only around the nesting islands or within a single national jurisdiction may not account for the full movement pattern documented here. The study record also notes shared migratory routes with other Red Sea rookeries. That finding supports attention to connected habitats and cross-border coordination, while not establishing that every rookery uses an identical route.
“Displacement” is the term reported in the indexed record. The figures describe separation between nesting and foraging areas for the tracked turtles; they do not by themselves describe the exact path each turtle took, how often it used each location, or how long it stayed there. The available record does not provide those details, so they should not be inferred from the distance range.

The distance span is useful less as a single benchmark than as a reminder that movements varied among the tracked animals. A conservation map focused on the nearest waters around a nesting island might capture some habitat but miss farther feeding destinations documented in the study. At the same time, the maximum figure is not a prescribed radius for a protected area: the record gives displacement to feeding grounds, not a tested boundary or a recommendation for how large a reserve should be.
What should conservation planning take from the study?
The most defensible takeaway is to plan around a connected set of habitats rather than a single beach boundary. For the NEOM Islands study, that means considering nesting beaches, inter-nesting areas including reef systems used by hawksbills, migratory routes, and feeding grounds. Because the mapped feeding grounds included waters in two countries, coordination across the Saudi-Egyptian boundary is also relevant.
- Include nesting sites. Shusha and Walah Islands are where the tracked turtles were nesting, so beach habitat remains part of the picture.
- Account for inter-nesting habitat. The study mapped areas used between nesting events, and its record highlights reef systems in hawksbill habitat.
- Consider routes, not only destinations. The study mapped migratory pathways and notes routes shared with other Red Sea rookeries. That points toward connected-habitat planning rather than isolated-site thinking.
- Include feeding grounds. The six identified areas were split between Saudi and Egyptian waters, making feeding habitat a cross-border consideration.
- Keep the evidence scale visible. The findings come from 17 tracked animals over two nesting seasons. They inform planning but do not describe all turtles or prove that a given protection measure works.
These habitat categories provide a useful way to compare the scope of possible planning approaches. A beach-only view covers the nesting location; a broader local view can also account for inter-nesting areas and reefs; a connected regional view adds routes and feeding destinations, including those across a national border. The study offers evidence of use across those categories, but it did not test which approach produces better conservation outcomes. The distinction is between documenting where tracked turtles went and proving that a particular management boundary or policy will protect them effectively.
In practical terms, the study supports asking whether plans account for all four parts of the movement picture—nesting beach, inter-nesting habitat, route, and feeding ground—and whether their geographic scope matches the recorded movements. It does not supply a ready-made map or answer every implementation question. The research record does not establish the protection status of the identified sites, specify a particular regulation, or assess whether a development proposal affects them.

This is a framework for interpreting the evidence, not a prescription for a specific boundary, regulation, or reserve. The indexed record does not establish the status of protection at the identified sites, assess particular development plans, or test a conservation intervention. Those claims would require evidence beyond the tracking findings summarized here.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What can this study prove—and what can it not?
It provides tracking evidence that the sampled turtles used areas beyond their nesting islands, traveled to feeding grounds over a wide reported displacement range, and used destinations in both Saudi and Egyptian waters. It also identifies reef systems as particularly relevant to hawksbill inter-nesting habitat and notes shared routes with other Red Sea rookeries. Together, those findings support considering connectivity in regional conservation planning.

It does not provide a census of the regional turtle population or establish how common each movement pattern is. The sample consisted of 17 turtles from two islands across two nesting seasons. Findings from that group should not be generalized to every turtle, every rookery, or every year in the Red Sea.
The available primary source for this article is an indexed PubMed record rather than an independently inspected full paper. Accordingly, this article does not add details about tag duration, statistical methods, threats, or reserve status that are not in the record. The study also does not show that any particular conservation plan has already delivered a successful outcome. Its value here is narrower and still important: it documents movement and habitat use that conservation decisions should take into account.

The scale of those movements was also emphasized by study coauthor Hector Barrios-Garrido, KAUST Senior Marine Megafauna Specialist, in a quotation reported by Devin Reese’s January 16, 2026, article for A-Z Animals. Barrios-Garrido said: “What stood out most was the scale of the travels that some of the hawksbill turtles made after nesting. While these turtles lay their eggs on relatively small islands in the NEOM region of Saudi Arabia, several individuals traveled hundreds of kilometers across the Red Sea to reach their feeding areas.” The quotation reinforces the study’s central point about distance, but it remains an account of an author email as reported in that secondary article.
Frequently Asked Questions
Do these results apply to every sea turtle in the Red Sea?
No. The study reports tracking results for a defined sample from two Saudi islands, not a regional population census. Movement patterns can differ among animals and rookeries, so the reported distances should not be treated as a rule for all Red Sea turtles.
Why does it matter that some feeding grounds were in Egyptian waters?
It shows that the tracked animals’ habitat use crossed a national boundary. That makes coordination between countries relevant when planning for connected routes and feeding habitat, even though the study does not evaluate any existing cross-border program.
Does the study show that a particular reef or beach is currently protected?
No. The findings identify habitat use and movement, but the indexed record does not establish protection status at the mapped sites. It also does not assess whether a specific reserve or regulation is effective.
What does satellite tracking add to a map of nesting beaches?
It can show where tagged animals move after nesting and identify areas used along the way or for feeding. In this study, that information revealed movements to sites in both Saudi Arabia and Egypt; it does not by itself explain every behavior or threat experienced along those routes.
What does the 34.8–501.7 kilometer range mean?
It is the reported range of displacement from nesting areas to feeding grounds for the tracked turtles. It is not a universal distance for sea turtles, and it does not describe the exact path, time spent traveling, or a recommended size for a protected area.
The Bottom Line
The NEOM Islands study tracked 17 nesting turtles to habitats beyond their beaches, including reef-associated inter-nesting areas and feeding grounds in Saudi and Egyptian waters. Its results support planning for connected habitats and routes, while remaining evidence from a small sample—not a population-wide map or proof that any specific conservation plan works.
