Conch (pronounced "konk") refers to several species of large marine snails that belong to the family Strombidae, with the queen conch (Lobatus gigas) being the most well-known. These sea creatures are instantly recognizable by their beautiful, spiral-shaped shells, often prized for their intricate patterns and stunning colors. Found in warm, shallow waters of tropical regions, especially in the Caribbean, conches play an important role in marine ecosystems by grazing on algae and maintaining the balance of their environment.
Culinary traditions in many coastal areas celebrate conch as a delicious and versatile seafood. From Bahamian conch salad to deep-fried fritters and hearty stews, conch meat is tender, slightly sweet, and packed with flavor. It is a beloved ingredient in island cuisines, where it is often prepared fresh and infused with local spices.
