Sinistrofulgur perversum and Busycon carica
This species shares many characteristics with another species, the knobbed whelk
- Lightning whelks are sinistral in coiling, whereas knobbed whelks are dextral
- Lightning whelks have a lower spire than the knobbed whelk
- The knobs of the lightning whelk are usually less well-developed than those of the knobbed whelk
- Lightning whelks are diurnal, while knobbed whelks are active both day and night
- Lightning whelks prefer to stay in deeper waters than the knobbed whelks when feeding on mud flats
Human use
For thousands of years Native Americans used these animals as food, and used their shells for tools, ornaments, containers and to make jewelry, i.e. shell gorgets.[3] They may have believed the sinistral nature of the lightning whelk shell made it a sacred object. The Minnesota Woman (lived c. 6000 BCE in modern Minnesota) wore a Sinistrofulgur perversum shell.[4]
The lightning whelk is the "State Seashell of Texas".[5]
