Raja Ampat, located in West Papua, Indonesia, is globally recognised as the epicentre of marine biodiversity, boasting an extraordinary concentration of coral and fish species. This region is critical for global marine ecosystems, with protected areas ensuring its unique flora and fauna thrive, offering opportunities for marine exploration and conservation.
The Unrivalled Biodiversity of Raja Ampat
Raja Ampat’s marine environment is nothing short of astounding. It holds the distinction of hosting 75% of all known coral species, a figure that underscores its immense ecological value. This vast archipelago, comprising 610 islands with only 34 inhabited, is a sanctuary for marine life.
The sheer number of species found here is staggering. Over 1,300 to 1,800 reef fish species have been documented, with the Dampier Strait alone accounting for 1,427 species. Furthermore, the region is home to 550+ coral species, including over 500 reef-building corals per eco-region, and approximately 700 mollusc species. These figures firmly establish Raja Ampat as the heart of the Coral Triangle, the area with the highest marine diversity recorded on Earth.
Raja Ampat’s Marine Protected Areas (MPAs) cover approximately 35,000 km², safeguarding around 45% of its coral reefs and mangroves.
Marine Mammals and Endemic Species
Beyond corals and fish, Raja Ampat supports a remarkable diversity of marine mammals and endemic species. Seventeen marine mammal species inhabit these waters, including sperm whales, orcas, dugongs, dolphins, and Bryde’s whales, offering incredible chances for encounters during expeditions. Five species of sea turtles, including the endangered Hawksbill turtle, also find refuge here. The region is also celebrated for its endemic species, such as the Wobbegong Shark, Epaulette Shark, Pygmy Seahorse, Mantis Shrimp, and Ghost Pipefish, which are found nowhere else on Earth.
Conservation Efforts and Protected Areas
The sustained health of Raja Ampat’s marine ecosystems is largely attributed to rigorous conservation efforts. The total marine area spans 12,565,197 hectares, designated as a UNESCO Biosphere Reserve in 2025. The broader reserve area encompasses 13,382,438 hectares. A network of 10 Marine Protected Areas (MPAs) covers approximately 35,000 km², safeguarding around 45% of the region’s coral reefs and mangroves. These protective measures have yielded positive results, with 60% of the reefs reported to be in good to excellent condition.
