Located at the southern end of the great expanse of Lake Malawi, with its deep, clear waters and mountain backdrop, the national park is home to many hundreds of fish species, nearly all endemic. Its importance for the study of evolution is comparable to that of the finches of the Galapagos Islands.
Located at the southern end of the great expanse of Lake Malawi, the property is of global importance for biodiversity conservation due particularly to its fish diversity. Lying within the Western Rift Valley, Lake Malawi is one of the deepest lakes in the world. The property is an area of exceptional natural beauty with the rugged landscapes around it contrasting with the remarkably clear waters of the lake. The property is home to many hundreds of cichlid fish, nearly all of which are endemic to Lake Malawi, and are known locally as "mbuna". The mbuna fishes display a significant example of biological evolution. Due to the isolation of Lake Malawi from other water bodies, its fish have developed impressive adaptive radiation and speciation, and are an outstanding example of the ecological processes.
Criterion (vii): The property is an area of exceptional natural beauty with its islands and clear waters set against the background of the Great African Rift Valley escarpment. Habitat types vary from rocky shorelines to sandy beaches and from wooded hillsides to swamps and lagoons. Granitic hills rise steeply from lakeshore and there are a number of sandy bays.
