Abstract:
Fast snapping in the carnivorous Venus flytrap (Dionaea muscipula) involvestrap lobe bending and abrupt curvature inversion (snap-buckling), but how dothese traps reopen? Here, the trap reopening mechanics in two differentD.muscipulaclones, producing normal-sized (N traps, max.≈3 cm in length)and large traps (L traps, max.≈4.5 cm in length) are investigated. Time-lapseexperiments reveal that both N and L traps can reopen by smooth andcontinuous outward lobe bending, but only L traps can undergo...     »
