Detailed structure of the terminal spine and aesthetasc-like setae on the spinneret-leg tip of Sinelobus sp. a conventional SEM image of the distal end of the terminal spine of pereopod 3 (thread-spinning) (b) reconstructed terminal spine from SBF-SEM scans of pereopod 3 shows ducts merging at the tip. c conventional SEM image of the dactylar setae of pereopod 4 (non-thread-spinning). d reconstructed sagittal plane through the dactylar setae from SBF-SEM scans of pereopod 4. e conventional SEM image of the dactylar setae of pereopod 3. f transverse plane at the base of dactylar setae from a SBF-SEM scan of pereopod 3. Abbreviation: nds, nervous divisions innervating dactylar setae. Scale bars, 1 μm for a, b, 0.5 μm for c, d, 0.3 μm for e, f
