Likoma Island is the larger of two islands in Lake Malawi, in East Africa, the smaller being the nearby Chizumulu. Likoma and Chizumulu both belong to Malawi, and together they make up the Likoma District. Although both islands lie just a few kilometres from Mozambique, and are entirely surrounded by Mozambican territorial waters, they are both exclaves of Malawi. The island has an overall area of 18 km2, and is located in the north-eastern part of Lake Malawi, 7 km north-west of Cobue, Mozambique). The closest town on the Malawian coast is Chintheche.
Despite a high population density, the natural environment of Likoma island is largely unspoiled. The coast is varied, with rocky slopes, sandy bays and swamps. The interior of the island is mostly covered by grassland, with a large number of baobab trees (of the Adansonia digitata species) and mango trees. Fauna is mostly composed of small reptilians, amphibians, birds and a number of invertebrates, including scorpion spiders. On the coast, crocodiles are occasionally seen. The waters around Likoma, as is usual in Lake Malawi, host a number of cichlids; some species, such as Labidochromis caeruleus likomae, are endemic of the Likoma area.
