The Cone Seashell is typically straight-sided, with a tapering body whorl, low spire, and narrow aperture (the opening into the shell’s first whorl). Cones inject a paralyzing toxin by means of a dart; a few of the larger species have fatally stung humans. The usual preys are worms and mollusks, and a few cones capture fish.
The Cone shell toxins are widely used by neurobiologists to study receptor and ion channel functioning invertebrates. Most cone species occur in the Indo-Pacific region.
