Corals

Corals are fascinating marine organisms that play a vital role in the health and biodiversity of ocean ecosystems. They belong to the phylum Cnidaria and exist in symbiotic relationships with microscopic algae called zooxanthellae, which provide them with energy through photosynthesis.

Corals form colonies of tiny polyps that secrete calcium carbonate to build intricate, rock-like skeletons, forming the framework of coral reefs. These reefs serve as essential habitats for countless species of fish, invertebrates, and other marine life, supporting one of the most diverse ecosystems on Earth. While they come in various forms, including hard corals like SPS and LPS, and soft corals like zoanthids and mushrooms, all corals are incredibly valued for their beauty, ecological importance, and vulnerability to environmental changes such as rising sea temperatures and ocean acidification.
