Material Before Morphology: Substrate‐Dependent Mechanical Tuning of Radular Teeth
Advanced Materials Interfaces, EarlyView.Substrate‐dependent material tuning in Clausilia radular teeth. Closely related taxa retain a conserved gross tooth morphology, but differ in elemental composition and mechanical properties according to feeding substrate. Rock‐associated taxa show increased Ca–Si enrichment and higher stiffness and hardness, especially in the central radular region ...
