Whelk

Several different species of large whelks in the family Buccinidae on sale at a fish market in Japan

The whelk is a sea snail which is carnivorous or a scavenger; it does not eat algae, unlike the conch which it resembles. [2] Many kinds of whelks have historically been used, or are still used, by humans for food.

Although many whelks are quite 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, not very closely related, families of sea snails.

Usage

The common name 'whelk is also spelled welk or even wilks. The word originally comes 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 using this common name vary a great deal from one geographic area to another.
