Conch, a large marine mollusk having a spiral shell. The shells are often beautifully colored and are made into jewelry or are used as ornaments. When held to the ear, the shell acts as an amplifier for the normally inaudible noises within the ear.
Conchs are found in tropical oceans all over the world. The meat of the queen conch is used to make conch chowder and conch fritters. The queen conch sometimes produces a hard mass called a conch pearl. It is usually pink and elliptical and is highly valued as a gem. The fighting conch attacks other animals. It lives in shallow coastal waters from South Carolina to Florida and west to Texas. All conchs are endangered.
Conchs belong to the class Gastropoda. The queen conch is Strombus gigas; the fighting conch is S. pugilis alatus .
