English: Movie of the reconstructed primordium from the E8 to E20 stages. The top half of the frame shows the dorsal surface of the primordium and the bottom half shows the left surface; color coding as in Fig 1E. Key frames are presented with brief descriptions in Fig 2. The intestine and the body of the embryo begin elongating at about 377 minutes, and the body begins muscle movements at 409 minutes. The start of int ring rotation is visible at 313 minutes by the apparent dorsal shift in the positions of 3R and 4R (light purple and light blue, respectively). This bulge protrudes between the dorsal muscle quadrants and into the overlying dorsal hypodermal cell, and can be seen in the transverse views of embryos shown in S3D Fig between 321 and 337 minutes.
