The word "conch" refers to a type of marine mollusk with a spiraled shell, but there are many synonyms that can describe similar shellfish. For example, whelks, periwinkles, and limpets are all types of sea snails that have similar shells to conchs. Clams, oysters, and mussels are all bivalve mollusks that are commonly found in shallow coastal areas. Additionally, abalone and nautilus are two other types of shellfish that have very distinctive and ornate shells. While the word "conch" is often associated with Caribbean cuisine, exploring other synonyms can reveal a diverse range of fascinating shellfish from around the world.
