Figure 3 in Glide-leflection symmetly in deutelostomes: an evolutionaly pelspective

Figure 3. Somitomeric glide-reflection symmetry in chimaeroid fishes. A* dorsal view of synarcuale (SA) and anterior neural arches of alizarin-stained preparation of Chimaera monstrosa MSU; ID1* first pair of interdorsal elements (photo by Vladislav A. Gorin). B* C* Chimaera monstrosa ZIN 34419. B* left-dorsal view of CT-scan-based 3D reconstruction of calcified rings (CR) in the notochordal sheath and calcified parts of basidorsal (BD)* and interdorsal (ID) elements of neural arches of the pectoral trunk region (see Supporting Information* Model S2); the lips of basidorsal elements are indicated which border the outlets for the ventral nerve root. C* ventral view of the spinal canal enclosing the spinal cord (SC) and ventral nerve roots (VNR) of the pre-anal trunk region. D* X-ray dorsal view of Hydrolagus ogilbyi (image by Artem M. Prokofiev). Arrowheads on (A) and (D) point at the left (pink) and the right (blue) foramina in the posterior blades of synarcuale.
