Fig. 3. Averaged reflectance spectra of the arm stripes of the squid (A) and the
cuttlefish (B) and corresponding partial polarization spectra from the squid
(C) and the cuttlefish (D). Data collected in Position 2 (see
Fig. 1). Different colored
curves in each figure represent spectra obtained from a sample tilted from
0° to 60° in increments of 10° (the key in A also applies to
B–D). Note that identical reflectance values between spectra occurred in
some cases (which are mathematically not possible to analyze); hence, some of
the values in partial polarization curves are not plotted.
