Although their anatomy is simple, these animals and their architectural abilities play a starring role in complex coral reef communities. The polyp also uses oxygen for respiration and in turns, returns carbon dioxide to the zooxanthellae. Among the brain coral’s closest friends and associates are zooxanthellae. This species of reef-building coral has a hemispherical, brain-like shape with a brown, yellow, or grey colour. These neuromorphic nanostructures are in turn formed by the self-organization of uniform nanosized ZSM-5 crystals. Individual polyps look like tiny anemones. These polyp-bearing valleys are each separated by grooved ambulacral ridges. Wildscreen's Arkive project was launched in 2003 and grew to become the world's biggest encyclopaedia of life on Earth.
