Lake Matano also known as Matana, is a natural lake in South-Sulawesi, Indonesia. It is the deepest lake in Indonesia (ranked by maximum depth), and the 8th deepest lake in the world.
Lake Matano is home to many species of endemic fish and other animals as well as many plants.
The endemic fishes of Matano have been compared to that of the species swarms of the Rift Valley Lakes of Africa. While not as diverese they are thought to have all arisen from a single ancestor species and diversified into numerous different species which now fill many of the previously vacant ecological niches.
The waters of Lake Matano are exceptionally clear, visibility is good, and many of the fish species are highly dependent on visual cues and colour perception for their mating behaviour
