Wetlands are among the most productive ecosystems on Earth and among the most drained. Species whose habitats mention wetland, marsh, swamp, estuary, mangrove, or floodplain are listed here.
Wetlands — marshes, swamps, mangroves, and floodplains — filter water, buffer floods, and nursery fish, amphibians, waterbirds, and reptiles at the land–water edge.
Alligators, herons, otters, and mangrove specialists illustrate how wet soils and shallow water create unique niches.
Drainage, pollution, invasive plants, and coastal development erase wetland habitat and the species that need it.
Use freshwater for inland rivers and lakes, and ocean for fully marine coasts.
Ranked by profile popularity. An animal may also appear in other biomes if it uses multiple habitats.

Wetlands — marshes, swamps, mangroves, and floodplains — sit at the edge of land and water. They filter nutrients, buffer floods, and provide nursery habitat for fish, amphibians, waterbirds, and reptiles. Many wetland species decline when wetlands are drained or polluted.
Species lists on this page are drawn from Global Animal Guide profiles whose habitat facts match wetland keywords. Browse the ranked list for answer-first guides covering diet, range, and conservation.
Wetlands is defined by climate, vegetation, and water availability that favour particular body plans and behaviours. Compare sibling biome hubs (ocean, forest, desert, and more) to see how the same animal groups specialise differently.
