Reefs are vital marine ecosystems, ranging from biologically-formed coral and oyster reefs to artificial structures enhancing biodiversity. They provide habitats for a multitude of species, play a crucial role in ecology, and offer insights into geological history. Artificial reefs also contribute to marine health and protect shorelines.

Reefs are formed by the accumulation of biological material or the deposition of non-living geological substances
Biotic Reefs
Biotic reefs are formed by living organisms, such as corals and algae, and provide habitats for a vast array of marine life
Abiotic Reefs
Abiotic reefs are formed from geological processes and can be found in a variety of marine environments
Reefs play a vital role in maintaining biodiversity, providing clues about past climates and environments, and contributing to the formation of natural resources
Coral reefs are formed by the symbiotic relationship between corals and zooxanthellae algae
Tropical Coral Reefs
Tropical coral reefs are the most diverse and extensive types of reefs, providing habitats for a vast array of marine life
Other Biogenic Reefs
Other biogenic reefs include oyster reefs and sponge reefs, which are built by the accumulation of calcium carbonate and silica, respectively
Coral reefs can be categorized by their shape and relationship to landmasses, including fringing reefs, barrier reefs, and atolls
Artificial reefs are human-made structures placed in marine environments to replicate the functions of natural reefs, and can be made from various materials such as ships, concrete, and specially designed modules
Artificial reefs enhance marine biodiversity, provide opportunities for research and tourism, and can also protect shorelines from erosion and improve water quality
By providing new surfaces for colonization, artificial reefs contribute to the health and productivity of marine ecosystems
