Fig. 1From: Eumelanin and pheomelanin pigmentation in mollusc shells may be less common than expected: insights from mass spectrometryPigmented shell samples investigated for eumelanin and pheomelanin colouration. Evidence for eumelanin is marked with an asterix, evidence for both eumelanin and pheomelanin is marked with two asterix. (Scale bars are 1 cm)Back to article page
