That or while looking at the coral necklaces in the beach shop. Though coral looks like stone with little holes, it is actually a kind of sea polyp with a stony, hole filled skeleton. Sometimes the word coral refers to the skeleton itself. Because of the red color of Mediterranean coral, coral is also an adjective meaning pink-red.
