Reef: meaning, definitions and examples

marine biology

A reef is a structure consisting of rock, coral, or other materials that provides habitat for diverse marine life. Reefs are typically found in shallow coastal waters and can play a critical role in the marine ecosystem by protecting coastlines, supporting biodiversity, and providing resources for fishing and tourism. Coral reefs, in particular, are among the most biologically diverse ecosystems on Earth and are often referred to as the 'rainforests of the sea.' However, they are under threat from climate change, pollution, and overfishing.
