What is a "whelk"?

A whelk is a type of marine gastropod mollusk characterized by its spiral-shaped shell and muscular foot. Whelks are commonly found in coastal waters and are known for their scavenging habits. They feed on a variety of prey, including shellfish, crustaceans, and even other mollusks. Whelks use their strong foot to crawl along the ocean floor in search of food. They have a rough, textured shell that provides protection and can come in a range of colors, from dark brown to pale yellow. Whelks are often harvested for human consumption and are a popular ingredient in seafood dishes.
