The Marshall Islands are made up of twenty-nine atolls and five coral islands arranged in two parallel chains across an immense expanse of ocean. Their land area is minimal and very low-lying, but their lagoons are among the largest in the world: Kwajalein's encloses a body of inland water comparable in area to that of a small country. The Marshallese reefs, far from any large centre of population, keep their coral and fish communities in good condition, with an abundance of sharks unusual in the Pacific. In 2011 the country declared a shark sanctuary covering its entire exclusive economic zone, one of the largest on the planet at the time. Its beaches are green turtle nesting grounds.

Did you know?

Bikini atoll was the setting for twenty-three nuclear tests between 1946 and 1958, including one that left a crater two kilometres across on the floor of the lagoon. Decades later, that crater is covered in large corals and the lagoon is patrolled by sharks and reef fish at very high densities. The reason is as simple as it is uncomfortable: once the area became uninhabitable for people, fishing disappeared completely.

Biodiversity profile

Conservation

Bikini is a World Heritage Site as a testimony to the nuclear age. The shark sanctuary bans shark fishing and the retention of their fins across more than one and a half million square kilometres, although effective surveillance over so vast an area remains a challenge.

Where and when to watch wildlife

Bikini, with restricted access, for reefs and sharks. Namdrik and the southern atolls for seabirds and turtles. The northern lagoons between March and October for mantas and cetaceans.

Diving and snorkelling

Bikini Atoll

The floor of the atoll, where the ships sunk in the American nuclear tests of 1946 (Operation Crossroads) now rest, among them the aircraft carrier USS Saratoga and the Japanese battleship Nagato.
