A swamp is a temperate biome where swamp huts containing witches and black cats generate, slimes and frogs can spawn. The main biome is forested with oak trees covered with vines, dead bushes, mushrooms and blue orchids.

Description[]
Swamps have elevations low enough to go below sea level throughout much of the area. A large portion of swamps are flooded, where patches of clay are found on the lakebed. Dry areas of this biome feature relatively flat terrain with a few tall grass and sparse oak trees. Water in swamps takes on a gray-green color at the surface, turning pale yellow when submerged in it. Unlike other Overworld biomes, swamps have varying temperatures, which affects the color of grass blocks, grass and leaves. Swamp vegetation includes dead bushes, mushrooms and oak trees which can grow in shallow water and generate with vines growing on them. Sugar cane is found often growing on shores, while seagrass litters the bottom of flooded areas. Besides dandelions and poppies, blue orchids grow among the grass while lily pads dot the surfaces of lakes; both are found exclusively in swamps. In Bedrock Edition, huge mushrooms can generate as well.
A swamp may include a swamp hut, housing a witch and a black cat. Only witches can spawn in and around the hut. Swamps, alongside deserts, can generate fossils, fairly rare structures found underground.
Slimes may spawn in swamps at low light levels exclusively between elevations of Y=50 and Y=70. Their spawn rate is affected by the moon phase, spawning most often during full moon and not spawning at all during new moon.
Villagers that spawn in swamps get a unique swamp-themed look. While villagers have swamp-specific types, no village featuring exclusively these villagers can be generated. The only way for these villagers to spawn is either by being bred in swamp or curing a zombie villager that spawned in a swamp.
Swamp biomes are usually found in flat terrain near sea level in regions with very high erosion values and they also replace rivers in these areas. Swamps can be found in many temperature clusters with the exception of snowy regions.
Variants[]
Although this biome currently has only a single variant, one removed variant (swamp hills) could be found in previous versions as well as one upcoming variant (Mangrove Swamp) in the wild update.

The swamp biome is the standard swamp variety. In Java Edition, some parts of the swamp may have marsh-like terrain, where the grass has multiple single blocks of water generating within it. At nighttime, depending on the moon phase, slimes may spawn at Y-levels 50-70 alongside other hostile mobs, making swamps the only places aboveground where slimes can be found. Swamp huts and fossils structures also generate in this biome.

The mangrove swamp is a variant of the swamp biome that generates in warmer regions, usually next to jungles and deserts. The foliage in this biome is very dense featuring plenty of mangrove trees which vary a lot in height. The floor is mainly composed of mud blocks with occasional grass patches. The grass has the same color as the normal swamp but leaves and vines have a unique light green tint and the water is teal rather than gray. Frogs are the only passive animals that spawn in this biome and all frogs spawned here are warm frogs.
