Development of the Axolotl

Synopsis

Studies the early stages of the development of the axolotl, an aquatic salamander with emphasis on genetically-determined characteristics. Two wild-type dark axolotls are mated, each is heterozygous for white and albino mutations. Time-lapse photography is used to show cleavage to the blastula stage, gastrulation and neurulation. Rotation and elongation of the embryo are shown followed by identification of the gills, somites and eyes. The embryo breaks free of the vitelline membrane and a later stage shows well developed gills, heart and eyes. Final scenes show the dark, golden albino, white and white albino larvae.
