Red mangroves (Rhizophora mangle) grow to heights of 40 feet tall. They are known for their congestion of red-colored prop roots that extend down from the trunk and lower branches and anchor the tree in the mud or sand. When submerged at high tide this tangle of roots provides hiding places for fish, and also serves as substrate for a variety of encrusting organisms such as barnacles, oysters, sponges and tunicates which in turn provide food for those fish.
Their propagules (pre-germinated seeds) reach lengths of 12 inches and are dispersed by tidal currents. The baby mangrove seedlings can travel by water for up to one year before finding a suitable location to set down their roots.
