Coral reefs are intricate underwater ecosystems formed by colonies of tiny marine organisms known as corals. These reefs provide critical habitats for a diverse array of marine life, including fish, mollusks, and sea turtles, contributing to biodiversity and the health of ocean ecosystems. Coral reefs, often referred to as the 'rainforests of the sea,' are particularly sensitive to environmental changes, such as rising ocean temperatures and acidification, which pose significant threats to their survival. Conservation efforts are essential to protect these vital ecosystems, which also support local economies through tourism and fishing.
