life science Maturity 11-13 Next article →

A whelk is a term used for several different species of carnivorous sea snails. Most whelks are characterized by a shell that is tapered and features a swirling shape. While many people use the name for many types of snails, most true whelks belong to the family Buccinidae. Other snails, such as the dog whelk, may also be called whelks even though they belong to families that are not closely related. These marine animals play significant roles in ocean ecosystems as predators.

True whelks, which are members of the Buccinidae family, follow a specific predatory process to eat. They are carnivores, meaning they hunt and consume other living animals. Their diet includes various prey like annelids, crustaceans, mussels, and other molluscs. To find these animals, whelks use chemoreceptors, which are specialized organs used to sense chemical signals in the water. Once they locate a target, they use a unique method to eat. They drill holes directly through the shells of their prey. This allows them to reach the soft tissues inside the shell.

There are many different types of whelks categorized by their scientific families. The family Buccinidae contains the true whelks, including species like the common whelk of the North Atlantic. The family Muricidae includes the dog whelk, which is also known as Nucella lapillus. Another family, the Ranellidae, includes species in the genus Cabestana, which are called predatory whelks in Australia and New Zealand. In the West Indies, the family Trochidae includes the Cittarium pica, a large edible top shell.

Humans have interacted with whelks throughout history for many different purposes. In antiquity, the dog whelk was used to create a rich red dye. This specific dye was noted for improving in color as it aged over time. In the United Kingdom and Ireland, certain species like Buccinum undatum are common edible whelks. During the Victorian era in London, whelks were a popular street food. Vendors often sold them near public houses and theatres to people walking by.

Culinary uses for whelks vary greatly depending on the geographic region. In Japan, whelks are frequently prepared as part of sashimi or sushi dishes. Vietnam features a dish called Bún ốc, which consists of sea snails served with vermicelli. In Korea, a popular dish includes whelks in a salad with chili sauce and cold noodles. This has been a common side dish served with alcohol for many generations. In the United States, species in the genera Busycon and Busycotypus are commonly eaten.

Whelk meat is also a significant source of nutrition for those who eat it. A single reference serving of whelk provides 24 g of protein. It also contains 8 g of carbohydrates and 0.34 g of fat. Certain species hold special status in specific locations. For example, the knobbed whelk is the official state shell for both Georgia and New Jersey. Other notable species include the channeled whelk, the lightning whelk, and the red whelk.

Beyond food, whelks hold cultural and symbolic importance in various societies. In Brazil, empty shells are used in a traditional Afro-Brazilian divination game. This practice is called jogo de búzios and is performed by older women of African ancestry. In different parts of the world, the names for these animals change constantly. In Scotland, the word whelk is sometimes used to refer to the periwinkle. Because the name applies to so many different families, the definition of a whelk depends on where you are in the world.
