Threadlike cilia-bearing tentacles probe for food, such as forams, detritus, and even the occasional buried bivalve, and bring it to the mouth where a large radula grinds it up.
Once the prey is snared it is bitten with strong beak-like jaws and pulled into the mouth by the radula .
In some chitons, the radula has teeth tipped with magnetite, which hardens them.
Most mollusks use the radula to break up food, but the cone snail uses it to inject venom.
Major interneurons fire cyclically during feeding in the radular retraction phase of the protraction/retraction cycle and drive many other retraction neurons.
