Figure 3 in The shell-eyes of the chiton Acanthopleura granulata (Mollusca, Polyplacophora) use pheomelanin as a screening pigment
Figure 3. High-performance liquid chromatography (HPLC) elution profile of the degradation products of the pigment that we extracted from the valves of the chiton Acanthopleura granulata (where absorption was set at 280 nm). The solid line represents the digestion product of the extracted pigment. For reference, the dashed line represents the same digestion reaction minus the pigment. The inset shows an elution profile for the degradation products of synthetic pheomelanin (DOPA-cysteine melanin) from Panzella et al. (2007), a paper whose methods we replicated. We hypothesize that the distinct peak that we see at 30 min in our elution profile represents BTCA, a diagnostic degradation product of pheomelanin.
Figure 2 in The shell-eyes of the chiton Acanthopleura granulata (Mollusca, Polyplacophora) use pheomelanin as a screening pigment
Figure 2. Absorption spectra of the pigment that we extracted from the valves of the chiton Acanthopleura granulata. The black line represents freshly extracted pigment. The grey line represents the same sample of pigment after it had been digested in alkaline hydrogen peroxide for 14 h. Note that digestion by hydrogen peroxide causes: (1) the absorption peak in the visible wavelengths to drop and shift towards shorter wavelengths; and (2) the appearance of degradation products that absorb strongly in the UV wavelengths. Both of these observations are consistent with the degradation of pheomelanin by hydrogen peroxide.
Figure 1 in The shell-eyes of the chiton Acanthopleura granulata (Mollusca, Polyplacophora) use pheomelanin as a screening pigment
Figure 1. The results of using sodium hydroxide to extract pigment from the decalcified shell plates of the eyed chiton Acanthopleura granulata. (A) An image taken before bleaching, where the dark spots are the rings of screening pigment associated with the shell-eyes (the arrow points to a single eye). The same red-brown pigment is expressed around the shell-eyes and, more broadly, in the proteinaceous extra-cellular matrix that surrounds the eyes and aesthetes. (B) The same valve after 48 h in 1 M sodium hydroxide at room temperature. The scale bar represents 1 mm.

Haplotypes are denoted as circles, their size is proportional to number of individuals carrying respective haplotype. Numbers at branches represent numbers of mutational steps (displayed for n> 1). Three main haplogroups are marked by ovals.
