Tritons and frog shells are solid with rugged spiral cords interrupted by thick varices, marking prior growth phases, and parallel folds on the columella.  Most are coated by a bristly or leafy brown periostracum.  Frog shells add a tubular posterior canal while Distorsios have a broad parietal shield greatly reducing the aperture.  They use corrosive saliva to subdue and liquefy prey including gastropods, bivalves, echinoderms, or worms.

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.
