Brain corals are found in shallow warm-water coral reefs in all the world's oceans. They are part of the phylum Cnidaria, in a class called Anthozoa or flower animals. The lifespan of the largest brain corals is 900 years. Colonies can grow as large as 1.8 m (6 ft) or more in height. Brain corals extend their tentacles to catch food at night. During the day, they use their tentacles for protection by wrapping them over the grooves on their surface. The surface is hard and offers good protection against fish or hurricanes.

The purpose of mucus is to lubricate and protect the organs that it lines.he cilia in the nose play a major role in the sense of smell. The  cilia transmit the smell to the olfactory nerve. They also catch  toxins like chemicals, viruses, and bac â¦ teria and cause them to  become trapped in mucus and swallowed instead of being inhaled into  the lungs.
