Pneumatophores (new-MAT-oh-forz) are the black mangrove tree’s way of breathing in areas with low oxygen. Although they are unrelated to each other, mangrove species (there are three in Florida) all display some sort of root adaptation. The predominant tree in this image is a red mangrove, identified by with its arching red prop roots, while the black mangrove (hidden behind the red mangrove here) has a root structure that spreads out far and wide and is topped with these pencil-like tubes that provide aeration for the tree.
