Comparison of median and lateral eye visual systems in (c) Amblypygi, (d) Scorpiones, (e) Araneae, and (f, g) Xiphosura. a, b, 3D serial reconstruction of the visual system of whip spider Heterophrynus elaphus. c, Amblypygi (Damon medius, Heterophrynus elaphus, Phrynus spp.), this study. d, Scorpiones (Euscorpius spp., Androctonus australis), after Lehmann, et al. [33] and Fleissner [40]. e, Araneae (Cupiennius salei), after Strausfeld, et al. [28], Strausfeld, et al. [29]. f, g, Xiphosura (Limulus polyphemus), after Lehmann, et al. [33], Calman, et al. [38], Chamberlain, et al. [39]. L1, first lateral eye visual neuropil; L2, second lateral eye visual neuropil; M1, first median eye visual neuropil; M2, second median eye visual neuropil; M/L2, region were M1 and L1 overlap
