shoot; L. porus - a pore or passage]. The opening between the
archenteron and outside of the
embryo, formed by invagination during
gastrulation. In some
organisms, it becomes the
anus.

deuterostomes.

site of
gastrulation initiation and later the opening of the
archenteron at the vegetal region of certain
embryos (e.g., echinoderm and amphibian); in
deuterostome embryos it is the future
anus of the
organism.
