M.K. and J.A. gratefully acknowledge support by the NSF Designing Materials to Revolutionize and Engineer our Future program (DMR 1533985). M.K. thanks the Alexander von Humboldt Foundation for a Feodor Lynen Research Fellowship and gratefully acknowledges financial support from the MIT Department of Mechanical Engineering. D.I.S. gratefully acknowledges support by the NSF (DEB-1354831). We thank A. Schwartzman, Y. Zhang, and S. Chen for their technical assistance and E. Belmonte and B. Anseeuw for providing photographs of A. granulata. D.I.S. collected and identified chiton specimens. M.J.C. and X.X. performed synchrotron experiments. M.J.C. and L.L. processed and analyzed data from synchrotron experiments. L.L. performed electron microscopy studies and mechanical tests with data analysis. M.J.C., G.T.E., M.K., and L.L. performed optical measurements and data analysis. M.K. wrote the ray-tracing program. M.J.C and M.K. performed ray-trace simulations. All authors interpreted results. L.L. and M.J.C. prepared figures, tables, and movies and wrote the draft manuscript. C.O. and J.A. supervised the project. All authors revised the manuscript for submission.
