Bivalves do not have a radula.

∙ 14y ago
One class of molluscs that lacks a radula is the Bivalvia, which includes clams, mussels, and scallops. Instead of a radula, these organisms have two shells that they use to filter feed. They do not require a radula for scraping or grazing on food sources like other molluscs.
