FEA of D. longicephala (A) CLSM projections of uninduced and induced form of D. longicephala. The red x indicates the region of max lateral width, in where the models were loaded for the simulations. (B) Heat maps of deformation and stress distribution in an uninduced animal model, loaded with a force of 1 mN. (C) Heat maps of deformation and stress distribution in an induced animal model (D) Heat maps of deformation and stress distribution in an uninduced model provided with the material properties of an induced animal. (E) Heat maps of deformation and stress distribution in an induced animal’s model with the material properties of an uninduced animal. (F) Empirical data of structural Young’s-modulus and critical force for uninduced and induced animals measured using a microindenter. (t-test, for structural Young’s-modulus measurement n (uninduced) = 83, n (induced) = 62; for critical force measurement n (uninduced) = 28, n (induced) = 18; Level of significance: *p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.005).
