An empty lightning whelk shell found on the beaches of Sanibel Island Florida.

The lightning whelk, scientific name Busycon perversum, is an edible species of very large predatory sea snail or whelk, a marine gastropod mollusc in the family Buccinidae, the busycon whelks. This species has a left-handed or sinistral shell. It eats mostly bivalves.

Sanibel Island and Captiva Island have earned their reputation as the Shell Islands. The islands are actually made out of shells, like some magnificent work of shell art created over thousands of years.

Shell-lovers from all over the world make pilgrimages to tiny Sanibel Island’s Gulf Coast, considered the best shelling spot in North America according to Travel & Leisure Magazine
