3D reconstructions of identified muscles within the walking leg (A, B), pushing leg (C, D), and male pedipalp (E, F), as modelled from iodine staining and micro-CT–scanning.

<p>A key is not included, as deeper muscles cannot easily be visualized in this figure. Individual muscles of specific prosomal appendages are illustrated separately in Figs <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0191400#pone.0191400.g005" target="_blank">5</a>–<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0191400#pone.0191400.g008" target="_blank">8</a>. Reconstructions in the left column (A, C, E) are all anterior views and reconstructions in the right column (B, D, F) are all posterior views. These reconstructions should be considered in conjunction with the cephalothoracic appendage reconstructions in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0191400#pone.0191400.g003" target="_blank">Fig 3</a>. The 3D versions of these files are available in the Supporting Information (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0191400#pone.0191400.s003" target="_blank">S3</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0191400#pone.0191400.s004" target="_blank">S4</a> and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0191400#pone.0191400.s005" target="_blank">S5</a> Figs).
