Swamp

 A swamp is a type of wetland characterized by water-saturated ground, often supporting the growth of dense vegetation, such as trees and shrubs. Swamps can be found in both tropical and temperate regions and are rich in biodiversity, providing habitats for various species of plants, birds, fish, and amphibians. 

Swamps play an important ecological role by acting as natural water filters, controlling floods, and storing carbon. They can be fresh or saltwater and often have slow-moving or stagnant water. Famous swamps include the Everglades in Florida and the Pantanal in South America.
