Fig. 5.Drawing of the bell #musculature of C. xamachana and pictures of details of stained #ephyrae. Both drawing and pictures follow the same orientation, with the top of each figure facing towards the mouth of the ephyra, and the bottom facing the periphery of the bell. (A) Schematic drawing of a C. xamachana ephyra's musculature observed from the oral side. (B) Phalloidin-stained fraction of the oral side of the ephyra, from the base of the oral arms to the rim of the bell. (C) Phalloidin-stained detail of the transition (top to bottom) from the innermost circular coronal band to the undulated coronal band. (D) Phalloidin-stained close up of the intersection (top to bottom) of the outermost coronal muscles with the radial musculature. rm = radial muscles; cm = coronal #muscles. PX and DT indicate proximal and distal ends from oral arms. Arrows indicate undulated muscles band, asterisk indicate circular coronal muscles. Scale bar B = 100 µm. Scale bar C, D = 50 µm.
Fig. 1.Stereo microscope pictures of C. xamachana ephyrae showing growth of intact and bisected ephyrae. (A) Trajectory of growth in the original ephyra with photographs at days 0, 7, 14, 21, and 28. (B) Visual progress of two fragments with circle back comparison to original medusa, all are on the same scale (see scale bar). Locations of rhopalia are pinpointed with black dots, edges of the bell and oral arms are outlined in black. See description of one ephyra regeneration and development in Supplementary Material.
This IOB paper has not only incredible research on
#Regeneration and Musculature in Halved #Cassiopea xamachana #Ephyrae, but it also amazing images!
