What do mollusks use for crawling digging and catching prey?

Mollusks use their muscular foot for various functions, including crawling, digging, and catching prey. The foot can adapt to different environments; for example, it allows gastropods to move along surfaces or burrow into sand. In predatory mollusks like octopuses, the foot has evolved into tentacles, which they use for capturing prey. Additionally, some bivalves can use their foot to anchor themselves or dig into substrates for protection.
