Pneumatophores of mangrove plant Pneumatophores differentiate the black mangrove and grey mangrove from other mangrove species. Fishers in some areas of Southeast Asia make corks for fishing nets by shaping the pneumatophores of mangrove apples ( Sonneratia caseolaris ) into small floats.
In botany, pneumatodes are air-containing structures in plant roots. [1] Their function is to allow gaseous exchange in root tissues. This can be beneficial to semi-aquatic plants, such as neo-tropical palms. [2]
The black mangrove (Avicennia germinans) lives on higher ground and develops many specialized root-like structures called pneumatophores, which stick up out of the soil like straws for breathing. [ 22 ] [ 23 ] These "breathing tubes" typically reach heights of up to 30 cm (12 in), and in some species, over 3 m (9.8 ft).
Aerenchyma in stem cross section of a typical wetland plant. Aerenchyma or aeriferous parenchyma [1] or lacunae, is a modification of the parenchyma to form a spongy tissue that creates spaces or air channels in the leaves, stems and roots of some plants, which allows exchange of gases between the shoot and the root.

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.

The shrub does not grow more than about 20 m (66 ft) high. The roots are shallow and send up a large number of pencil-shaped pneumatophores. These aerial roots help with gas exchange and also play an important part in the exclusion of salt from the plant's vascular system. [3]
