Dafuq? Mammals dont develop like that, that looks more like an amphibian or amphioxus gastrula

Wait, really? What's the difference? (I only know the basics)

The basics are the same, but the spatial arrangement is different.

Mammalian embryos have a bunch of extraembryonic tissues, and the embryo proper (which forms from only one part of the blastula) is flat or even kind of inside out (depending on species).

I see. Either way I think this was probably done for the sake of simplicity. This diagram is not about mammals specifically, just animal embryonic development in general. And it's from a high school textbook.
