Montserrat is a Caribbean island that is a British overseas territory. It is located in the Leeward Islands, part of the chain of islands known as the Lesser Antilles, in the West Indies. The island of Montserrat measures approximately 16 km (9.9 mi) long and 11 km (6.8 mi) wide, with approximately 40 kilometres (25 mi) of coastline. Montserrat is nicknamed The Emerald Isle of the Caribbean both for its resemblance to coastal Ireland and for the Irish ancestry of some of its inhabitants. Montserrat, like many isolated islands, is home to some exceptionally rare plant and animal species. Montserrat is also home to the Critically Endangered Giant Ditch Frog (Leptodactylus fallax), known locally as the Mountain Chicken, found only in Montserrat and Dominica.
