Figure 3

Morphological changes at the junction between the intestine and rectum during the embryonic development of the red stingray. (a) Schematic drawing of the distal part of the digestive tract. Transversal sections through the rectum show that the rectal canal is not fully developed and closed in stage 30-32 embryos (b-d), but is opened in stage 33 embryos (the latest stage) (e). Scale bar = 100 µm.
