When Pedipes ovalis withdraws into its shell, its foot is sequestered between the parietal and the columellar teeth, while the sinus above the parietal tooth encloses the portion of the mantle skirt with the pneumostome. This organization suggests that one function of the long parietal tooth characteristic of the genus is to prevent the snail’s foot from blocking the pneumostome.
