Figure 3. A, B in Somatic musculature of Tardigrada: phylogenetic signal and metameric patterns

Figure 3. A, B, musculature of Milnesium cf. tardigradum (A, dorso-lateral view; B, ventro-lateral view). C, D, musculature of Acutuncus antarcticus (C, lateral view; D, ventro-lateral view). Ph, pharynx. Letters and numbers identify the muscle attachment points (see text). Nodes of ventral muscle groups are marked by hexagons; attachment points and nodes of lateral muscle group are marked by squares; attachment points and nodes of dorsal muscle group are marked by circles. A–D, CSLM, maximum projection. B, C, colour coded by depth. Scale bars: A–D = 50 μm.
