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. Monkeys, birds, insects, and other plants all live in mangrove branches. Globally, mangroves are estimated to occupy an area of 152,361 km2. Mangroves categorized as secretors, including species in the black mangrove genus Avicennia, push salt from the ocean water out through special pores or salt glands within their leaves. The roots even hold onto those sediments which leads to better water quality and a reduction in erosion.
