Official State Shell of Texas
Texas designated the lightning whelk (Busycon perversum pulleyi) as the official state shell in 1987. All Marine-Life Symbols
Large and distinctive; the lovely Lightning Whelk is found only in the Gulf of Mexico and Southeast Atlantic coast of the USA. The lightning whelk is one of the very few shells that normally opens on its left side (most spiraling shells open to the right). Lightning whelks grow to one foot in length (though 15 inches has been recorded). Strong summer storms often wash large shells ashore - if you should find a live whelk, please put it back in the water where it belongs.
Whelk shells have inhabited these waters for 60 million years and have been significant to human cultures. Native Americans used whelks as food, housewares and weapons; the natural shape of the shell lends itself to practical uses (for instance, large whelks of all kinds have been used worldwide as lamps).
Even Whelk egg cases were utilized. Long ago, sailors used sandy clumps of egg strands to scrub themselves. Left-handed shells are considered sacred in parts of Asia and India, where a left-hand Whelk is very rare, so sailors visiting the Western hemisphere collected the common left-handed Lightning Whelk to sell for a profit in the East. This commerce continues today.
