Sanctuary Overview & Marine Topography
Located in French Polynesia, Anau Lagoon & Turtle Pass (Bora Bora) (-16.5004° N, -151.7415° W) stands as one of the world’s most dependable and ecologically significant habitats for wild sea turtles. Sustained by thriving benthic foraging grounds and sheltered coastal bathymetry, resident and migratory Green Sea Turtle (Chelonia mydas), Hawksbill (Eretmochelys imbricata) frequent these shallows daily for feeding, thermoregulation, and shell cleaning.
During peak months (May, June, July, August, September, October), visitors experience a verified 90% sighting probability. The optimum window for calm surface conditions and maximum underwater clarity is Morning 08:30-12:00, when offshore thermal breezes remain gentle and sunlight penetrates directly to the seabed.

Foraging & Cleaning Guild Dynamics
- Grazing Mechanics: Green turtles feed continuously on dense patches of marine seagrass and macroalgae, keeping the beds cropped and healthy.
- Cleaning Stations: Over time, turtle shells accumulate algae and parasitic organisms. Turtles hover over specific coral bommies where specialized cleaner wrasses, surgeonfish, and angelfish clean their carapaces and skin folds.
- Ascent Corridors: As air-breathing reptiles, turtles ascend to the surface every 5 to 15 minutes while feeding. Always maintain a clear vertical corridor above resting or grazing turtles.
