Plants adapted for life in salty marshes are called halophytes. Halophytes are plants that are adapted to grow in soils that have high salt concentrations, such as those found in salt marshes, mangrove swamps, and other coastal areas. They have unique adaptations that allow them to take up and tolerate salt, such as specialized salt glands and the ability to store excess salt in their tissues. These adaptations enable halophytes to survive and thrive in environments where other plants would perish due to the high salt concentrations.
