What does corals mean?
Corals are fascinating marine animals that play a crucial role in the ecosystem of coral reefs. These tiny creatures are actually colonies of tiny animals called polyps, which work together to create the hard, calcium carbonate exoskeleton that gives coral its characteristic shape. Corals come in a variety of shapes and sizes, from delicate sea fans to massive brain corals. They are found in warm, shallow waters around the world and are an important food source for many marine animals. Despite their importance, corals are facing numerous threats, including climate change, pollution, and overfishing. As a result, many coral reefs are dying, and it is essential to take action to protect these vital ecosystems. By learning more about corals and their role in the ocean, we can work to preserve these incredible creatures and the ecosystems they inhabit.

Etymology of corals
The word 'coral' comes from the Latin 'corallium', which means 'sea lily'. This refers to the fact that corals are often mistaken for flowers or lilies due to their colorful and delicate appearance. The term 'coral' has been used in English since the 14th century to describe these marine animals.
Usage notes
Corals are often used to describe the hard, calcium carbonate exoskeletons of these animals, but they can also refer to the animals themselves. In formal writing, it is often more precise to use the term 'coral' to describe the exoskeleton and 'coral animal' or 'polyp' to describe the individual animal. In informal writing, the term 'coral' is often used to describe both the exoskeleton and the animal.
