Figure 15 in The Macrobiotus ariekammensis species complex provides evidence for parallel evolution of claw elongation in macrobiotid tardigrades

Figure 15. Macrobiotus kirghizicus from the Kyrgyz Republic – buccal apparatus and the oral cavity armature seen in PCM: A, dorsoventral projection of the entire buccal apparatus; B, C, oral cavity armature visible from dorsal (B) and ventral (C) view, respectively; D, oral cavity armature visible from lateral view; E, macroplacoid morphology. Filled flat arrowheads indicate the third band of teeth in the oral cavity, empty arrow indicates dorsal cuticular spike, empty flat arrowhead indicates the second band of teeth in the oral cavity, empty indented arrowheads indicate central constrictions in first macroplacoid and subterminal constriction in second macroplacoid. Scale bars in µm.
