evidence: Serrana Bank is not to be confused with Serranilla Bank. US sovereignty over two insular areas, Serranilla Bank and Bajo Nuevo (Petrel Island) is disputed. Serranilla Bank and Bajo Nuevo are in the Caribbean Sea, located approximately 180 miles southwest from the southern coast of Jamaica. Serranilla Bank is a roughly circular coral bank; on its southeast side are three small coral-and-sand keys, or low islands, the largest of which is a half mile in length. Bajo Nuevo, an oval-shaped coral bank situated northeast from Serranilla Bank, has two reefs; at both ends of each reef are small keys, the largest of which is about 300 by 50 yards in size. The United States has long maintained claims to both Serranilla Bank and Bajo Nuevo under the Guano Islands Act. Both areas are claimed by Columbia and Jamaica. Serranilla Bank is also claimed by Honduras. Nicaragua has not claimed these areas by name, but has stated that it claims all islands and cays located on its continental shelf; however, there is no agreed maritime boundary between Nicaragua and Columbia, or between Nicaragua and Honduras, in the Western Caribbean. Currently, the United States conducts maritime law enforcement operations in and around Serranilla Bank and Bajo Nuevo consistent with US sovereignty claims.
