The dog whelk, dogwhelk, or Atlantic dogwinkle (Nucella lapillus) is a species of predatory sea snail, a carnivorous marine gastropod in the family Muricidae, the rock snails. Nucella lapillus was originally described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae as Buccinum lapillus (the basionym ).
Whelks are any of several carnivorous sea snail species [1] with a swirling, tapered shell. Many are eaten by humans, such as the common whelk of the North Atlantic. Most whelks belong to the family Buccinidae and are known as "true whelks." Others, such as the dog whelk, belong to several sea snail families that are not closely related.
[4] [6] [7] The venom of the geography cone snail is a complex mix of hundreds of different toxins that is delivered through a toxoglossan radula, a harpoon-like tooth propelled from an extendable proboscis. There is no antivenom for a cone snail sting, and treatment consists of keeping victims alive until the toxins wear off. [4]
The practice of rearing snails for food is known as heliciculture. For purposes of cultivation, the snails are kept in a dark place in a wired cage with dry straw or dry wood. Coppiced wine-grape vines are often used for this purpose. During the rainy period the snails come out of hibernation and release most of their mucus onto the dry wood/straw.

The radula works like a file, ripping food into small pieces. Many snails are herbivorous, eating plants or rasping algae from surfaces with their radulae, though a few land species and many marine species are omnivores or predatory carnivores. Snails cannot absorb colored pigments when eating paper or cardboard so their feces are also colored. [3]
