A succession originates in a water body (aquatic environment) is called Hydrosere or hydrarch succession. Such a succession does not necessarily lead to the development of a land community. If the water body is sufficiently large and with wave action, the succession usually results in the formation of a large aquatic climax community. The important characteristic of hydrosere are given below :
1. Hydrosere usually starts from a pond.
2. Phytoplankton will be the pioneer community.
3. A forest or grassland will be the climax community.
4. Includes several seral stages of plant and animal communities.
5. Seral communities of a plant are more obvious than animals.
