Data from: Deciphering an extreme morphology: bone microarchitecture of the Hero Shrew backbone (Soricidae: Scutisorex)
<p>Biological structures with extreme morphologies are puzzling because they often lack obvious functions and stymie comparisons to homologous or analogous features with more typical shapes. An example of such an extreme morphotype is the uniquely modified vertebral column of the hero shrew <i>Scutisorex</i>, which features numerous accessory intervertebral articulations and massively expanded transverse processes. The function of these vertebral structures is unknown, and it is difficult to meaningfully compare them to vertebrae from animals with known behavioral patterns and spinal adaptations. Here we use trabecular bone architecture of vertebral centra and quantitative external vertebral morphology to elucidate the forces that may act on the spine of <i>Scutisorex</i> and that of another large shrew with unmodified vertebrae (<i>Crocidura goliath</i>). µCT scans of thoracolumbar columns show that <i>S. thori </i>is structurally intermediate between <i>C. goliath</i> and <i>S. somereni </i>internally and externally, and both <i>Scutisorex</i> species exhibit trabecular bone characteristics indicative of higher <i>in vivo</i> axial compressive loads than <i>C. goliath.</i> Under compressive load, <i>Scutisorex </i>vertebral morphology is adapted to largely restrict bending to the sagittal plane (flexion). Although these findings do not solve the mystery of how <i>Scutisorex</i> uses its byzantine spine <i>in vivo</i>, our work suggests potentially fruitful new avenues of investigation for learning more about the function of this perplexing structure.</p>
