Mangrove is used to refer both to the tree and to the ecosystem.
Mangroves are halophytic trees found in salty, saturated soils.
Mangroves are found in tropical regions between the Cancer and Capricorn tropics. There are two big groups of mangroves with only one similar species. In the west, the species are found in the genera Auicennia germinaus, Rhizophora mangal, Rhizophora racemosa , and Lagoncularia racemoas . In the east, the genera are Auicennia marina, Rhizophora mucronata, Lumitzera, Nypa , and several others. The speciation of mangroves is the same as that for seagrasses and corals.
