Throughout the tropics where reefs are accessible, coral skeletons are used as building material, either in blocks or slaked to create cement. Another use for cnidarian skeletons is in jewelry. The pink colour known as "coral" is the hue of the skeleton of a species of hydrocoral. For predators they are filter feeders. They are also reef builders and early indicators of environmental change. Humans also use cnidarians in commerce and medicine.
