Tritons have solid shells with prominent spiral sculpture interrupted by varices, vertical ridges that are remnants of the shell's aperture from earlier stages of growth.  There is a short siphonal canal at the anterior end or base of the shell.  Most live shells are covered by a periostracum composed of brown bristles giving them a hairy appearance.   Tritons use corrosive saliva to subdue and liquefy prey including mollusks and echinoderms.

Frog shells are named for the rough texture resembling a toad.  They are similar to tritons with the addition of a posterior notch, or series of notches, that may form tubes along the aperture's outer lip.  They prey upon worms and shells are often heavily encrusted with coralline algae.
