👉 Reef fluid, also known as biofilm exudate, is a complex mixture of organic compounds secreted by the microorganisms living within and on coral reefs. This fluid plays a crucial role in reef health and function, providing essential nutrients to the coral polyps while also acting as a defense mechanism against pathogens. It contains a variety of bioactive molecules, including polysaccharides, proteins, and secondary metabolites, which help maintain the delicate balance of the reef ecosystem. Reef fluid also facilitates nutrient cycling and supports the settlement and growth of new coral larvae, contributing significantly to the resilience and biodiversity of coral reef communities.
