Dynamical Numerical Model of the Molluscan Radula in its Interaction with the Substrate and Food Particles

Abstract: The radula, a chitinous membrane with teeth, is the molluscan autapomorphy for food gathering and processing. Even though this structure is studied for decades, the interplay between the structure and the particular food or/and the substrate remains mostly enigmatic. Here, we provide a numerical model approach to understand the relationship between structure, feeding efficiency, and partial work performed by the system. This first simple dynamic numerical radular model interacts with the food particles and the uneven substrate. This protocol can be applied to any system in the future, as the parameters (interaction between structures, adhesion, size of food particles, attachment angle of teeth to membrane, etc.) can be easily altered. This will shed light on the biomechanical adaptations of this feeding structure (e.g., wear and failure prevention) to the specific environment.
