Propagules of Rhizophoraare able to grow over a year after they are released from their parent tree, while the white mangrove, Laguncularia racemosa, floats for up to 24 days, though it starts losing its ability to take root after eight. With only about 80 species of true mangrove trees worldwide, mangrove ecosystems comprise a relatively low number of habitat-forming tree species, but a high diversity of decomposer, detritivorous and consumer species. Rich in tanninscompounds that are notable for their influence on the taste of red winemangrove bark is used in the tanning of animal skins to make leather. The mounds are also excellent hideouts and homes for other creatures like snakes.
