摘要: Studies from a submersible on seamount off San Salvador (Bahamas) revealed diverse multilayered macrophyte community, with net productivity levels comparable to shallow water seaweeds although receiving only 1–2% of the light energy available at surface. Four zonal assemblages occur over depth range 81 268 m and consist Labophora-dominated group (81–90 m), Halimeda assemblage (90–130 Peyssonnelia (130–189 crustose coralline zone (189–268 m). This deep flora is composed unique deep-water taxa combined forms characteristics shaded, low-light conditions.
