See our page on fishes adapted to murky water . They are wet all year although the water level may change seasonally. These also form at the edges of slow-moving streams or rivers, edges of lakes and in floodplains of rivers in the lowlands. Flooded forests are among the most fascinating habitats. See our page on the flooded forest and its occupants.
Lakes are deep with permanent water, regularly supplied with an inflow of water.
In some, the water flows out again. In others, there is no outflow so the water becomes very salty as evaporation concentrates minerals in the water. Mangroves form at the border between fresh and seawater and have a very large variety of specialists. See our page on the fascinating mangrove habitat and its occupants. Bogs are wetlands with accumulating peat formed because decomposition is slow.
