Whelk
A whelk is a common name for several kinds of marine gastropod molluscs, especially members of the family Buccinidae, often called “true whelks.” They are predatory sea snails with coiled shells and are found in marine waters worldwide, particularly in colder regions.

Whelks are carnivorous and feed on other molluscs, worms, and carrion.
Classification and naming
“Whelk” is a common name applied to several marine gastropods, especially true whelks in the family Buccinidae. Some animals called whelks belong to other families and are not closely related.
Description
Whelks are sea snails with coiled, often thick shells and a siphonal canal or groove. Shell shape and colour vary by species, but many are elongated and adapted to a predatory lifestyle.
Habitat and distribution
Whelks are found in marine waters around the world, with many species favouring colder seas. They commonly live on sandy, muddy, gravelly, or rocky seabeds.
Diet and behaviour
Whelks are carnivorous and scavenging gastropods. They feed on other molluscs and worms, and some species also take carrion or prey captured in traps.
Human use
Some whelk species are harvested and eaten as seafood. In places such as Massachusetts and parts of the North Atlantic, they are commercially and recreationally important shellfish species.
Key facts
- Most whelks are marine gastropods, and the name is used for several different sea snail species rather than one single species.
- True whelks belong mainly to the family Buccinidae.
- Whelks are carnivorous predators and scavengers that feed on other molluscs, worms, and carrion.
- The common whelk (Buccinum undatum) is a well-known example and is the largest sea snail found in UK seas.
- Many species have elongated shells with a wide opening and a siphonal canal or groove.
Whelks are part of Canada’s marine biodiversity and are recognized in Canadian natural-history sources as carnivorous marine snails; some species are also relevant to shellfish harvesting and coastal ecology in Atlantic Canada.[16]
