Swamps are one kind of wetland biome. Like other wetland biomes, a swamp’s water must be clean in order for the wildlife in it to thrive. Readers learn the main features of both freshwater and saltwater swamps, as well as where some of the biggest swamps are on Earth.

Full-color photographs and inset maps aid readers in identifying this interesting biome in the world around them.
