 Endemic and near-endemic fishes from other families include "Glossogobius matanensis", "Mugilogobius adeia", "Nomorhamphus weberi" and "Oryzias matanensis".Many of the endemics are seriously threatened due to pollution and predation/competition from a wide range of introduced fishes, including flowerhorn cichlids.The water snake "Enhydris matannensis" is only known from the vicinity of Lake Matano and on Muna Island.
