The clear blue waters of Mataking Post Wreck are home to an impressive array of large pelagic species. Divers frequently encounter majestic eagle rays, graceful manta rays, elusive hammerhead sharks, and vigilant grey reef sharks. While not explicitly detailed, the wreck itself likely hosts a variety of smaller reef fish and invertebrates, adding to the biodiversity.
Visiting Mataking Post Wreck is best done by experienced divers due to the strong currents often present, which can also contribute to the presence of large pelagics.
