These outgrowths pinch off to form the mesodermal layer between the ectoderm and endoderm. Invertebrate Zoology. Compare Protostomia. Deutero in Greek translates to second, thereby, deuterostome translating to second mouth. N/A (Technically, Parazoa) Cnideria Protostome/Deuterostome. However, because we all develop along the same lines, we're more similar than it might appear at first glance. Therefore, they are neither protosomes nor deuterostomes like other Cnidaria members.

Finally, if the animals that have true tissues and bilateral symmetry also develop an anus first and mouth second during embryonic cell division, then they fit nicely into the category called deuterostome, which literally means 'second mouth.'. In Protostomia (proto meaning first and stoma meaning mouth), the mouth develops from the first opening into the embryonic gut i.e., blastopore. The mesoderm in deuterostome forms from the ingrowths of the archenteron.
