Figure 3: Stereo images of entire gammaridean specimens (use red-cyan glasses to view). (a) Red-cyan stereo anaglyph based on a pair of macrographs of Dikerogammarus villosus recorded under slightly different angles. (b)-(c) Images of Gammarus roeselii based on a micro-CT scan. (b) Volume rendering. This presentment emphasizes the outer surface structures. (c) Maximum intensity projection. This presentment enhances the inner structures, as outer surface structures appear transparent.
