blastopore
The opening of the archenteron, the primitive gut, to the outside, formed by invagination of cells on the embryo’s surface which form the mesoderm and endoderm during during gastrulation.In some animals, the blastopore becomes the anus; in others, it closes and the anus opens at or near the same site; in some animals (e.g., chickens), invagination gives rise to a virtual blastopore at the primitive streak.
