Reefs are absent in the Mediterranean mainly due to its relatively low nutrient levels and varying salinity, which don't support large reef-building corals. Historically, the Mediterranean Sea also experienced drastic environmental changes, like the Messinian salinity crisis, which negatively impacted reef growth. Despite the absence of extensive reefs, the Mediterranean hosts a variety of marine life and unique ecosystems.
