How Do Fringing Reefs Support Biodiversity Despite Their Small Size?

💡 The Answer

• Fringing reefs provide a mosaic of microhabitats – shallow flats, reef crests, steep slopes – each hosting distinct species.
• The intricate three-dimensional structure of coral creates countless hiding spots, increasing niche diversity.
• High primary productivity from algae and phytoplankton supports a dense food web, from tiny copepods to large sharks.
• Their location near land also brings nutrients from mangroves and seagrass beds, enhancing overall reef productivity.
