Teonai: Tikehau's Aquarium of Jacks and Sharks

Diving Teonai feels like entering a vast, living aquarium, a description that genuinely captures the density and diversity of marine life here. From the moment you descend, the sheer numbers of Atures (jack fish) are apparent. These schooling fish create dynamic, shimmering walls that shift and swirl with the current, encompassing you in an active, pulsating environment that is characteristic of Tikehau’s richer passes.

The dive profile at Teonai is adaptable, offering engagement at various depths. You can begin in shallower sections, ideal for experiencing the immediate vibrancy of the reef, before drifting deeper. The visibility often allows you to appreciate the full scale of the schools and the broader topography as you move through zones where these aggregations are most prevalent, an experience that deepens with each metre of descent.

Beyond the jack fish, Teonai is a consistent location for encounters with the more imposing residents of the lagoon. Keep an eye out for eagle rays (Aetobatus narinari) as they gracefully navigate the open water, their distinctive patterns and flowing movements making for memorable sightings. Their presence adds another layer to the pelagic activity, often appearing with an almost choreographed elegance against the backdrop of the reef.

Sharks are a significant feature of Teonai, with 'mamaru' sharks, likely local for tiger sharks (Galeocerdo cuvier) or even lemon sharks (Negaprion brevirostris), being regularly observed. Additionally, blacktip sharks (Carcharhinus melanopterus) are commonly seen, particularly in the shallower areas, making it a distinctive site for those undertaking their first dive. Their consistent presence makes for reliable, close-up encounters, a hallmark of diving in French Polynesia.
