Raja Ampat, an archipelago of over 1,500 islands scattered across the Indonesian province of West Papua, is widely regarded as the most biodiverse marine ecosystem on the planet.
For divers, it’s a dreamscape of technicolour reefs, exotic marine life, and remote, pristine waters – but what makes it so biologically extraordinary?
Located within the Coral Triangle – the global epicentre of marine biodiversity – Raja Ampat lies at a crossroads of ocean currents that funnel nutrients into the region. These rich waters support a staggering range of life: over 600 species of coral (around 75% of the world’s total) and more than 1,700 species of reef fish have been recorded here. From tiny nudibranchs to majestic oceanic manta rays and stealthy wobbegong sharks, the variety of life per square metre is unrivalled anywhere on Earth.
One of the key reasons for this diversity is the region’s isolation and relatively limited human impact. Raja Ampat’s remoteness has helped preserve its reefs and local communities, supported by conservation organisations, have established marine protected areas and sustainable tourism initiatives, allowing nature to flourish.
Diving here means encountering dazzling coral gardens at shallow depths, plunging vertical walls, drift dives through fast-moving channels, and submerged seamounts teeming with life. Sites like Cape Kri, Blue Magic, and Melissa’s Garden have achieved legendary status in the diving world, not just for the beauty of the reefs but for the sheer number of species seen on a single dive.
Raja Ampat isn’t just a place to tick off a bucket list – it’s a vital stronghold for global marine biodiversity. Scientists consider it a “species factory,” where new lifeforms are constantly evolving. Every dive offers the possibility of discovering something new, making it a hotspot for marine research as well as eco-tourism.
Raja Ampat’s legendary biodiversity is the result of natural abundance, evolutionary history, diverse habitats, oceanic connectivity, and strong conservation practices. It’s a living laboratory, a photographer’s dream, and a diver’s paradise — all rolled into one.
