any of several marine snails of the subclass Prosobranchia (class Gastropoda) comprising the genus Conus and the family Conidae. The shell is typically straight-sided, with a tapering body whorl, low spire, and narrow aperture (the opening into the shell's first whorl).

Most species occur in the Indo-Pacific region
