The mangroves are the group of trees and shrubs which grow in the saline water or brackish water. The mangroves grow in the region where the water of the river with low salt concentration mixes with the seawater with high salt concentration. This formed a region with a moderate level of salt concentration is known as estuary.
This water formed with moderate amount of salt is known as mesohaline water and the organism which grows in this water are known as euryhaline organism which can tolerate the wide range of salt concentration water like few species of fish, algae, sponges and many others.
