Schematic view of the fibrous network organization of mesoglea of A. aurita. For clarity, the diagram does not show actual sizes of the various structures. (Vertical arrows) Direction of the oral-aboral axis. Characteristic length-scales of jellyfish and mesogleal fibrous architecture network for adult jellyfish (solid) and juvenile jellyfish (shaded). Visualizations by DIC microscopy of the thick vertical and tangential fibers are shown in Fig. 2, A and B, respectively. Visualizations by SEM microscopy of the fine fibers are shown in Fig. 3. Endoderm (en); exumbrella (ex); fine fibers (ff); subumbrellar swimming muscle (mu); thick tangential fibers (tf); thick vertical fibers (vf). Figure adapted from Weber and Schmid (15).
