Historical Examples of blastopore
The opening of this sac is regarded by the authors as the blastopore.
From one end of the blastopore there is continued an opaque band.
This we consider to be the posterior end of the blastopore of the embryo.
The blastopore is elongated and slightly narrowed in the middle.
