What groups Of mollusks have radula?
Mollusks that possess a radula include gastropods (such as snails and slugs), bivalves (in some cases, like certain primitive species), and cephalopods (like squids and octopuses). The radula is a unique feeding organ that functions like a tongue, equipped with tiny teeth to scrape food from surfaces. However, many bivalves lack a radula, as they primarily filter feed.
