  1. ALGAE The focus will be less on taxonomy and more on the importance of algae in the coral/reef ecosystem

  2. Green Algae (Chlorophyta) Caulerpa sertularoides Halimeda Codium Caulerpa racemosa

  3. Brown Algae (Phaeophyta) Dictyota spp. Padina spp

  4. Galaxaura sp. Red Algae (Rhodophyta) Jania sp. Porolithium sp.

  5. Dinoflagellates (Pyrrhophyta)= Zooxanthellae

  6. Active removal of CO2 enhances carbonate precipitation

  7. FOOD SOURCE Corals are known microcarnivores, feeding on zooplankton; this source may not be sufficient to sustain coral only providing 10-20% of daily energy needs. Algae themselves are not be digested, but 94-98% of organic carbon produced by algae is utilized by the coral host. EXCRETION Zoothanthellae remove phosphorus as a waste product of coral. Dissolved phosphate may inhibit calcification. Zoothanthellae remove waste CO2 from coral.

  8. Blue-Green Algae (Cyanophyta) Black-band disease
