Although a number of whelks are relatively large and are in the family Buccinidae (the true whelks), the word whelk is also applied to some other marine gastropod mollusc species within several families of sea snails that are not very closely related.
True whelks are carnivorous, feeding on worms, crustaceans, mussels and other molluscs, drilling holes through shells to gain access to the soft tissues. Whelks use chemoreceptors to locate their prey. 
The common name "whelk" is also spelled welk or even wilks. The word originated from the Proto-Germanic root "weluka", which may come from the Proto-Indo-European root "wel-", meaning to turn or revolve. 
The species, genera and families referred to by this common name vary a great deal from one geographic area to another.

In Japan, whelks are frequently used in sashimi and sushi. In Vietnam, they are served in a dish called Bún ốc - vermicelli with sea snails.
In Korea, whelks are served with chili sauce in a salad with cold noodles. It is called ""Gol Baeng-ee Mu-Chim"(골뱅이 무침). Koreans often eat it as a kind of side dish when they drink alcohol and it has been a very popular side dish with alcohol for many generations.
