Fig. 2 in An integrative taxonomic approach to reveal the status of the genus Pomphorhynchus Monticelli, 1905 (Acanthocephala: Pomphorhynchidae) in Austria

Fig. 2. Proboscis and longitudinal row of hook roots of the three determined Pomphorhynchus species. All images are volume rendering of the 3-D stacks. In volume rendering each grayscale value is assigned a color according to an arbitrary colormap. The depiction depends on which values and how transparent they are displayed. In the present images a glow color map is used, which assigns graded colors from black (background) to shades of red-orange-yellow. A. Volume rendering of a confocal laser scan image stack of the proboscis of P. tereticollis. B. Volume rendering of the sectioned proboscis of P. bosniacus including reconstructed hooks as surface rendering. C. Volume rendering of the sectioned proboscis of P. laevis including reconstructed hooks as surface rendering. D-F. Internal view of the sectioned proboscids including a single longitudinal row of hooks. D. P. tereticollis. E. P. bosniacus. F. P. laevis. Legend: Red arrow = last circle of hooks; green arrow = extensions on basal hook roots of P. tereticollis; blue arrow = basal hooks attached in the middle of hook roots of P. bosniacus; yellow arrow: lack of extensions on basal hook roots of P. laevis. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
