The prop roots of a red mangrove suspend it over the water, thereby giving it extra support and protection. They also help the tree to combat hypoxia by allowing it a direct intake of oxygen through its root structure. A mangrove can reach up to 80 ft (24 m) in height in ideal conditions, but it is commonly found at a more modest 20 ft (6.1 m).
Rhizophora is a genus of tropical mangrove trees, sometimes collectively called true mangroves. The most notable species is the red mangrove (Rhizophora mangle) but some other species and a few natural hybrids are known. Rhizophora species generally live in intertidal zones which are inundated daily by the ocean.
Mangroves are hardy shrubs and trees that thrive in salt water and have specialised adaptations so they can survive the volatile energies of intertidal zones along marine coasts. A mangrove is a shrub or tree that grows mainly in coastal saline or brackish water. Mangroves grow in an equatorial climate, typically along coastlines and tidal ...

On the fringes of the sea 10 or 15 metres (33 or 49 ft) is a more typical height. The tallest trees are closest to the water and shorter trees are further inland. The tree has a large number of aerial stilt roots buttressing the trunk. The leaves are elliptical and usually about 12 centimetres (4.7 in) long and 6 centimetres (2.4 in) wide.
In some areas, mangrove reforestation and mangrove restoration is also underway. Red mangroves are the most common choice for cultivation, used particularly in marine aquariums in a sump to reduce nitrates and other nutrients in the water. Mangroves also appear in home aquariums, and as ornamental plants, such as in Japan. [citation needed]
The Philippines, with the fifth longest coastline in the world, holds at least 50% of known mangrove species and is considered one of the top 15 most mangrove-rich countries. Philippine mangrove forests cover an estimated 2,473.62 km 2 (955.07 sq mi) of coastline as of 2003, which comprise 3% of the total forest cover remaining in the country.
This is a list of mangrove ecoregions ordered according to whether they lie in the Afrotropical, Australasian, Indomalayan, or Neotropical realms of the world. Mangrove estuaries such as those found in the Sundarbans of southwestern Bangladesh are rich productive ecosystems which serve as spawning grounds and nurseries for shrimp, crabs, and many fish species, a richness which is lost if the ...
