Whelks are a type of shellfish mentioned in the How to Train Your Dragon Book series.
The term 'whelk' may be used for a variety of gastropods, but most often refers to species of the Family Buccinidae, or "True Whelks". Whelks generally have a cone-shaped and spiraled shell with an elongated lip on the opposite end. The animal inside is typically carnivorous - scavenging but also preying on other mollusks and even fish. They are able to bore holes into the shells of other invertebrates. Whelks also have an excellent sense of smell.
The Common Whelk (Buccinum undatum) is a numerous species located in the North Atlantic and is often seen in the British Isles and Scandinavia. They need a cold habitat and cannot survive in warm or hot temperatures.
In reality, whelks are a food item for humans. Their shells may also be used as a collectable item.
