The locomotory leg 10 of Scutigera coleoptrata. A Distal tip of tarsus 2 and pretarsal claw in ventrolateral view (SEM). B Maximum intensity projection overlay (CLSM) with excitations at 405 nm (blue), 458 nm (purple), 488 nm (cyan), 561 nm (yellow) and 633 nm (red). C-H Single channels for individual excitations. C Excitation at 405 nm. D Excitation at 458 nm. E Excitation at 488 nm. F Excitation at 514 nm. G Excitation at 561 nm. H Excitation at 633 nm. I EDX mapping of Na in tarsus 2 and the pretarsal claw.
