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.
