Ngerumekaol Pass, also known as Ulong Channel, partially cuts through the reef near the Island. [3] The channel stretches about 500 metres (1,600 ft), with an average width of 33 metres (108 ft) and leads into a coral reef lagoon. [2] There are sharks within the currents of the channel and Ulong Corner. The channel contains giant clams and one of the largest known patches of green lettuce coral in the world. [4] [5] Uruktapel is the largest island southward of Koror; at about 2 miles (3.2 km) off its western point is Ulong. Denges and Eil Malk Passages are passable, but navigation may be difficult in the lagoon between them and Ulong Island. From Ulong to Malakal Harbor, the lagoon is navigable. [6]
Henry Wilson (1740–1810), an English naval captain of the British East India Company was aboard his packet ship Antelope, when it shipwrecked off Ulong Island in 1783; [7] he returned to England with the local Prince Lee Boo. In the late 1700s, the island's inhabitants attempted to defend Ulong from attack along Ikesakes Reef but, having been defeated, were forced to leave. [8] There are Palau Cave Paintings on the island. [9]

An atoll is a ring-shaped island, including a coral rim that encircles a lagoon partially or completely. There may be coral islands or cays on the rim. Atolls are located in warm tropical or subtropical parts of the oceans and seas where corals can grow. Most of the approximately 440 atolls in the world are in the Pacific Ocean.
A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. Lagoons are commonly divided into coastal lagoons and atoll lagoons. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world.
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups.
