Marine phenomena refer to various natural events and processes that occur in the ocean. These can include bioluminescence, where certain marine organisms like jellyfish and plankton emit light, creating stunning displays in the water. Other phenomena include ocean currents, which are large-scale movements of seawater that influence climate and weather patterns around the globe. Another fascinating marine phenomenon is the formation of coral reefs, which are built by tiny animals called coral polyps. These reefs provide habitat for a diverse range of marine life and are vital for maintaining healthy ocean ecosystems. Additionally, events like red tides can occur when certain algae bloom excessively, impacting marine life and water quality.
