 parent tree, have dropped into water shallow enough for them to take root. A vast

2. Two species of mangroves are seen growing together in Biscayne Bay, 10 miles south of 

 Miami. Black mangrove {Avicennia nitida) on the left has an extensive underground 

 root system and sends up numerous pneumatophores, or breathing roots, that project 

 from the mud and sand. Red mangrove {Rhizophora ?nangle) on right has characteristic 

 prop roots and aerial roots. (Photo by the author.)
