That definition is fine if you live in the eastern USA. However, in the
Bahamas and West Indies (and Belize) a "whelk" is Cittarium pica, an
herbivore. In the northeast US and British Isles a "whelk" is Buccinum
undatum, a buccinid, and in the southern US it's any Busycon, in the family
Melongenidae, which are carnivores.
Conchs, called "Conchas" in Spanish, can be most anything, including
Muricidae, in Mexico and Central America. Even Cassis (which we call Helmet
shells) are known as Conchs in the Bahamas.
The answer to the difference is "depends on where you live". Common names
are only helpful in local situations. We need to use Latin to be sure other
shellers know what we're talking about!
