Mangrove roots above and below water. Mangrove plants require a number of physiological adaptations to overcome the problems of low environmental oxygen levels, high salinity, and frequent tidal flooding. Each species has its own solutions to these problems; this may be the primary reason why, on some shorelines, mangrove tree species show ...
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).

The generic name is derived from the Greek words ριζα (rhiza), meaning "root," and φορος (phoros), meaning "bearing," referring to the stilt-roots. [3] The beetle Poecilips fallax is a common pest of these trees, especially Rhizophora mucronata and Rhizophora apiculata. This beetle (related to carver beetles) lays its eggs in the ...
Example of aerial roots in the rubber fig (Ficus elastica) Due to the habitat in which R. apiculata occurs, the roots possess a special trait designed to anchor the plant to the soil. [4] [9] It still acts as a normal root through in-taking both water and nutrients with the only difference being it descends from the branches. Aerial roots ...
The red mangrove grows closest to open water. It has multiple prop roots, which may help to stabilize the soil around its roots. Further inland is the black mangrove lacking prop roots, but does have pneumatophores, which grow up from the roots to above the water level. The white mangrove grows further inland.
Many mangrove forests can be recognised by their dense tangle of prop roots that make the trees appear to be standing on stilts above the water. This tangle of roots allows the trees to handle the daily rise and fall of tides, which means that most mangroves get flooded at least twice per day.
Avicennia germinans, the black mangrove, [3] is a shrub or small tree growing up to 12 meters (39 feet) in the acanthus family, Acanthaceae.It grows in tropical and subtropical regions of the Americas, on both the Atlantic and Pacific Coasts, and on the Atlantic Coast of tropical Africa, where it thrives on the sandy and muddy shores where seawater reaches.
