Raja Ampat Marine Life
Mantas, Whale Sharks, Endemics & Macro

The global epicenter of marine biodiversity. 75% of all known hard coral species, 1,427 documented reef fish, world-record 374 species on a single dive at Cape Kri. From oceanic mantas to endemic walking sharks — encounters unavailable anywhere else.
Raja Ampat's biodiversity is quantifiable. The archipelago sits at the confluence of the Indian and Pacific Oceans, fed constantly by the nutrient-rich Indonesian Throughflow that fuels every level of the food chain — from plankton blooms to apex predators. The result: a 40,000 km² network of fringing reefs, barrier reefs, patch reefs, and atolls of unmatched complexity.
