Raja Ampat Islands is a place that has the potential to serve as a tourist attraction, especially diving tourist. Raja Ampat Islands waters according to various sources, is one of the 10 best waters for diving sites around the world. In fact, it may also be recognized as number one for the completeness of underwater flora and fauna at this time.

Dr. John Veron, coral experienced experts from Australia, for example, in a site he revealed, the Raja Ampat Islands are located in the most western tip of New Guinea, about 50 miles northwest of Sorong, has the best reef areas in Indonesia. Approximately 450 species of coral had been identified during the two weeks of research in that area.

Team of experts from Conservation International, The Nature Conservancy, and the National Institute of Oceanography (LON) Indonesian Institute of Sciences (LIPI) have done a quick assessment in 2001 and 2002. The result, they noted in these waters there are more than 540 species of hard corals (75% of total species in the world), more than 1,000 species of reef fish, 700 species of mollusks, and the highest record for gonodactyloid stomatopod crustaceans. It makes 75% of the world's coral species in Raja Ampat located. None of the places with the same area has a number of coral species as much as this.

There are several areas of coral reefs are still very good condition with the percentage of live coral cover by 90%, namely in the Dampier Strait (the strait between P. and P. Waigeo Batanta), Kofiau islands, archipelagic South East Misool and Wayag Islands. Types of coral reefs in Raja Ampat is generally fringing reef with gentle slope to steep contour. But also found atoll type and type of scorched or taka. In some places, such as in the village Saondarek, when the lowest tides, coral reefs can be seen without a dive and with his own adaptation, the corals can still be alive despite being in the open air and direct sunlight.

Unique species that can be encountered when diving is some kind of pigmy seahorse or kudalaut mini, wobbegong and manta ray. There is also endemic fish Raja Ampat, namely Eviota king, which is a kind of fish gobbie. At Manta Point supernal Arborek Dampier Strait, you can dive in the company of some tail Manta Ray is benign like when you dive in Derawan Islands, East Kalimantan. If you dive at Cape Kri or Chicken Reef, you can be surrounded by thousands of fish. Sometimes a collection of tuna, giant trevallies and snappers. But that stressful if we are surrounded by a collection of barracuda fish, even though it is relatively harmless (which is dangerous if we see barracuda solitary or alone). Reef sharks are also frequently seen, and if you are lucky you can also see turtles were secretly eating sponge or swim around you. In some places like in Salawati, Batanta and Waigeo also seen Dugong or sea cow.
