Older trees are distinguished by their dark, scaly bark, hence the name "Black Mangrove." The thick, leathery leaves secrete salt and the underside of the leaf is a lighter shade of green. The small, white flowers are fragrant and provide a great source of nectar for honey bees. Many root projections (pneumatophores) surround the tree.
Black mangroves grow along the coast in salt marshes. The many pneumatophores (root projections) create important habitat for crustaceans and small fish. The pneumatophores also help to filter sediment and reduce wave energy along the coast.
