The Coral is a type of marine invertebrate that belongs to the class Anthozoa. They are primarily found in warm, shallow ocean waters and play a crucial role in forming coral reefs, which provide habitat and protection for many marine species. Corals are made up of tiny, soft-bodied organisms called polyps that live in colonies and secrete calcium carbonate to create a hard skeleton. Coral reefs are often referred to as the "rainforests of the sea" due to their rich biodiversity. They support a wide variety of marine life, including fish, mollusks, and other invertebrates. However, coral reefs face threats from climate change, pollution, and overfishing, making their conservation essential for maintaining ocean health.
