Dive sites

The Federated States of Micronesia bring together more than six hundred islands spread across four states along almost three thousand kilometres of ocean. Pohnpei, mountainous and volcanic, is one of the rainiest places on the planet and keeps cloud forest on its summits, with plant species and birds that exist on no other island. Kosrae holds exceptionally well-preserved mangroves and reefs under little fishing pressure. Chuuk encloses an immense lagoon shut in by a coral barrier, on whose floor rests a fleet sunk during the Second World War that has become an artificial reef colonised by soft corals and fish. Yap, to the west, is famous for its waters and for its enormous stone discs traditionally used as money.

Nature in Micronesia

National animal: No official national animal

Did you know?

The waters of Yap hold a resident population of reef mantas that does not migrate and that comes every day to particular points on the reef known as cleaning stations, where small wrasse take on the job of removing their parasites and dead skin. Researchers have spent decades identifying individuals by the unique pattern of spots on their bellies, which has made it possible to follow the lives of particular animals for more than thirty years.

Biodiversity profile

Conservation

The regional Micronesia Challenge initiative committed the countries and territories of the region to protecting a significant percentage of their marine and terrestrial resources. The mangroves of Kosrae are among the best preserved in the Pacific and shield the coast from storms.

Where and when to watch wildlife

Yap between December and April for mantas at the cleaning stations. Chuuk year-round for wrecks colonised by coral. Pohnpei in the less rainy season for endemic highland birds.

Diving and snorkelling

Reef/Wall

Chuuk Lagoon (Truk Lagoon)

An atoll of 245 islands that was Japan's largest naval base in the Pacific. On 17 and 18 February 1944 the American Task Force 58 launched Operation Hailstone, sinking more than forty ships and destroying more than 250 aircraft. More than sixty wrecks lie on the lagoon floor today, most of them between 30 and 60 m and many practically intact.

Wreck

Fujikawa Maru (Chuuk)

An armed freighter sunk during Operation Hailstone and the most visited wreck in the lagoon. Her five holds contain the remains of dismantled Zero fighters, ammunition and war materiel. The engine room, amidships, runs over three levels and is the highlight of the dive.
