Difference between Series Proterostomia and Series Deuterostomia
The Major Difference between Series protostomia and Series Deuterostomia is that Series protostomia is a spiral division of the zygote, mouth arises from the blastopore while Series Deuterostomia is radial cleavage and Mouth is formed at some distance anterior.

Series protostomia | Series Deuterostomia |
| 1. Cleavage or division of the zygote is spiral or determinate. | 1. Cleavage is radial and indeterminate. |
| 2. The mouth arises from the blastopore or form anterior margin during development. | 2. Mouth is formed at some distance anterior to the blastopore and blastopore forms the anus during development. |
| 3. Coelom or body cavity is formed by the splitting of the mesoderm. This condition is called Schizocoelous. | 3. Coelom is developed as an outpouching of the archenterons. This condition is called Enterocoelous. |
| 4. Mesoderm is derived from the cells on lips of blastopore. | 4. Mesoderm is derived from wall of developing (Archenteron). |
| 5. This series Proterostomia includes animals belonging to phyla Aschelminthes (Nematoda) Annelida, Mollusca and Arthropoda. | 5. This series includes animals belonging to Echinodermata, Hemichordata and Chordata. |
