Cape Kri — The World’s Most Biodiverse Dive Site
The World Record Site
Dr. Gerald Allen’s record-setting species count at Cape Kri stunned the marine biology community and cemented Raja Ampat’s position as the global epicenter of marine biodiversity. To put 374 species in perspective: many popular dive destinations worldwide contain fewer total species across all their sites combined. At Cape Kri, this extraordinary concentration occurs on a single reef, on a single dive, in approximately 90 minutes of observation.
The secret lies in geography. Cape Kri’s position at Dampier Strait’s narrowest point accelerates tidal currents that carry nutrients from the Pacific Ocean into the strait. This nutrient conveyor belt supports an explosion of plankton growth, which feeds small fish, which attract larger predators, creating a complete marine food web of staggering complexity visible at every depth from the surface to beyond 30 meters.
What You’ll See
Fish Schools
Massive schools of barracuda, fusiliers, surgeonfish, and big-eye trevally create living walls of movement. Bumphead parrotfish cruise the reef in herds of 20-50. Schools so dense they block sunlight from the reef below. The biomass concentration at Cape Kri is visually overwhelming.
Reef Sharks & Predators
Blacktip, whitetip, and grey reef sharks patrol the current lines. Giant trevally hunt the reef edges. Napoleon wrasse approach divers with characteristic curiosity. Barracuda schools spiral in silver columns extending from reef to surface.
Reef Life
Every square meter of reef supports dozens of species. Anthias clouds in orange and purple, damselfish territories, butterflyfish pairs, angelfish, and wrasse species fill every niche. Hard coral coverage in excellent condition provides the foundation for this extraordinary ecosystem.
Macro Treasures
Pygmy seahorses on gorgonian fans (Hippocampus denise and H. bargibanti), ornate ghost pipefish, Pontoh’s pygmy seahorse, blue-ringed octopus, nudibranchs in extraordinary variety, and flatworms. Cape Kri rewards both wide-angle photographers capturing schools and macro specialists finding miniature marvels.
