Coral reefs are formed by the accumulation of calcium carbonate skeletons produced by tiny marine invertebrates called coral polyps.

Fringing reefs are found close to the shoreline and are directly attached to the coast.

The Great Barrier Reef, located off the coast of Australia, is the largest coral reef system in the world, stretching over 2,300 kilometers.

Atolls are typically found in the open ocean and are formed when a volcanic island subsides and the coral reef continues to grow upward.

Coral reefs rely on sunlight for photosynthesis by symbiotic algae living within their tissues.

Clownfish, also known as anemonefish, are famous for their symbiotic relationship with sea anemones and their ability to change color.

Coral bleaching occurs when corals expel the symbiotic algae living in their tissues, causing them to lose their color and become more susceptible to stress and disease.

Climate change, particularly rising sea temperatures and ocean acidification, is a significant threat to coral reefs worldwide.

Coral spawning is the process by which corals release eggs and sperm into the water, allowing for fertilization and the formation of new coral colonies.

Parrotfish play a crucial role in maintaining the health of coral reefs by grazing on algae and removing debris.

Coral communities encompass the diverse array of organisms living in and around coral reefs, including corals, fish, invertebrates, and algae.

Dolphins are intelligent and social creatures often seen near coral reefs, engaging in playful behaviors and interacting with other marine life.

Coral resilience refers to the ability of coral reefs to withstand and recover from disturbances, such as storms, bleaching events, or human impacts.

Oysters are marine bivalves that are known for their ability to produce pearls, which are formed as a defense mechanism against irritants.

Coral restoration involves human intervention to actively restore or create coral reefs, often using techniques such as coral transplantation and fragmenting.
