The structure of supernumerary limbs formed after 180 degrees blastemal rotation in the newt Triturus cristatus. 1983

S Papageorgiou, and N Holder

The structure of supernumerary limbs formed following 180 degrees ipsilateral blastema rotations in the arm of the newt Triturus cristatus is analysed. Both the skeletal pattern and the muscle patterns are examined. As is the case after comparable experiments in the axolotl (see, for example, Maden & Mustafa, 12982) the extra limbs which form show a range of anatomies. Limbs symmetrical about the dorsal-ventral and anterior-posterior axis are reported as well as some limbs which were part symmetrical and part asymmetrical. It is clear that newts and axolotls appear to react in similar ways to this particular experimental procedure.
