Corals are related to the sea anemones and have stinging tentacles around the mouth opening that are used to catch prey.

2. A hard, stony substance consisting of the skeletons of these animals. It is typically white, pink, or reddish and can form large reefs that support an abundance of ocean fish.

Etymology

Origin of coral

First recorded in 1275–1325; Middle English coral(l), from Latin corāll(i)um, from Greek korā́llion “red coral,” equivalent to korall- (from Semitic; compare Hebrew gōrāl “pebble”) + -ion diminutive suffix

Explanation

Coral is a marine polyp with a calcareous skeleton that lives in colonies. You probably last saw coral while scuba diving at the Great Barrier Reef. 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. Shakespeare wrote: “My mistress' eyes are nothing like the sun; Coral is far more “red than her lips' red.” Coral can also be a noun for unfertilized lobster eggs that turn red when cooking.
