| Most mollusks use the radula to break up food, but the cone snail uses it to inject venom. |
| In some chitons, the radula has teeth tipped with magnetite, which hardens them. |
| Once there, the gastropods use their belt of serrated teeth, called radula, to slice the living cordgrass. |
| Once the prey is snared it is bitten with strong beak-like jaws and pulled into the mouth by the radula. |
| The dog-whelk's radula drills into other animals such as barnacles, while the limpet's is used to rasp algae off rock surfaces. |
| Argonauta shares other characteristics with some Jurassic and Cretaceous ammonites, namely multicuspid rachidial tooth on the radula. |
