There are three species of trees that are considered mangroves: red (Rhizophora mangle), black (Avicennia germinans), and white (Laguncularia racemosa), although all are from different families.[75] All grow in oxygen-poor soil, can survive drastic water level changes, and are tolerant of salt, brackish, and fresh water.[76] All three mangrove species are integral to coastline protection during severe storms. Red mangroves have the farthest-reaching roots, trapping sediments that help build coastlines after and between storms. All three types of trees absorb the energy of waves and storm surges. Everglades mangroves also serve as nurseries for crustaceans and fish, and rookeries for birds. The region supports Tortugas pink shrimp (Farfantepenaeus duorarum) and stone crab (Menippe mercenaria) industries;[77] between 80 and 90 percent of commercially harvested crustacean species in Florida's salt waters are born or spend time near the Everglades.[73][78]
