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.
Star-shaped glial cells in the CNS are collectively known as astrocytes. 'Astro' implies 'star' and 'cyte' refers to 'cell'. Hence, we get 'astrocyte': a star-shaped cell. These glial cells are responsible for a lot of important things in the central nervous system; most notably, they are part of the blood-brain barrier. Tiny little feet leave the astrocyte and help to encircle the vessels that make up the blood-brain barrier, which is a barrier that helps to prevent undesirable substances from entering the brain via blood vessels.
