Conch (/kɒŋk, kɒntʃ/) is a common name applied to a number of different medium to large-sized shells. The term generally applies to large snails whose shell has a high spire and a noticeable siphonal canal (in other words, the shell comes to a noticeable point at both ends). In North America, a conch is often identified as a queen conch, indigenous to the waters of the Bahamas. Queen conchs are valued for seafood, and are also used as fish bait. The group of conchs that are sometimes referred to as "true conchs" are marine gastropod molluscs in the family Strombidae, specifically in the genus Strombus and other closely related genera. For example, see Lobatus gigas, the queen conch, and Laevistrombus canarium, the dog conch.
