The intersection of the spiral ribs and the axial sculpture results in a strong nodulose pattern of more or less round knobs.

The strong axial varices are often in two continuous series per whorl, one down each side of the shell.

The central tooth is saddle-shaped, with long basal limbs, each bearing a cusp-like spur upon its face.

The female snail lays her eggs enclosed in a jelly-like matrix that she sometimes broods with her foot.

Frog shells are active predators, and appear to feed on bristle worms (Polychaeta) that they anaesthetize with acidic saliva through their extensible, distally flattened probosces.
