Busycon

Whelks (living)

Busycon, Busycotypus and Sinistrofulgur are the knobbed, channelled and lightning whelks of the US east coast, large predatory snails whose shells are the most common big shells on Atlantic beaches; the lightning whelk is left-handed and is the Texas state shell. Their egg-case strings ('mermaid's necklace') wash up too. Fossil Busycon fill the Pliocene beds; see the taxon article.
