Mangroves



Mangroves are various types of trees and shrubs that are found in saline coastal areas in the tropics and subtropics. However, unlike normal trees, these mangroves in  the above picture have roots above the ground which is also know as pneumataphores as shown in the picture above. This structure allows oxygen to be transferred to the  roots trapped below ground in the low-oxygen soils.
Also, these roots are also highly impermeable and are highly suberised which act as an ultrafiltration mechanism to exclude sodium salts when taking in water.
