Features of Amphibian Gastrulation

Major features of amphibian gastrulation are:

  • Ectoderm surrounds the embryo by Epiboly.
  • Gastrulation is initiated by a limited invagination of endodermal cells.
  • Formation of archenteron is completed as a result of involution of endoderm.
  • Gastrulation begins on the future dorsal surface of the embryo.
  • Blastocoel is finally obliterated.
  • Mesoderm and most endoderm are internalized by involution over dorsal, lateral and ventral lips of blastopore.
