Protostomes and Deuterostomes are two groups of coelomates. In addition, cell development in protostomes is determinate. Archenteron forms in deuterostomes, but not in protostomes. Nerve cord in protostomes is ventral while nerve cord in deuterostomes is dorsal. Moreover, there is a difference between the two in terms of the formation of archenteron, nerve cord, as well as cell development. Furthermore, embryonic development occurs via spiral cleavage in protostomes while it occurs via radial cleavage in deuterostomes.īody parts of deuterostomes are more evolved and sophisticated than protosomes. In the former, the blastopore develops into the mouth while in the latter, the blastopore develops into the anus. The fate of blastopore is different in these two groups. Protostomes include many invertebrates while deuterostomes include echinoderms and chordates. What is the Difference Between Protostomes and Deuterostomes?
Protostomia in Greek means the mouth first, as the blastopore eventually becomes the mouth in protostomes.

They primarily differ in the way their mouth and anus are formed during embryonic developments. Protostomes and deuterostomes are the two main types of coelomate animals, and there are many differences between them. It would be particularly important to consider animals with a coelom, which is a fluid-filled cavity lying between endoderm (gut) and mesoderm (mostly muscle layer) in other words, coelom is the peritoneum in mammals.
In understanding these two terms it would be important to pay attention to how the embryonic development of organisms takes place. Another major difference is that embryos of protostomes undergo spiral cleavage while embryos of deuterostomes undergo radial cleavage. The key difference between Protostomes and Deuterostomes is that in protostomes blastopore becomes the mouth while in deuterostomes it becomes the anus.
