The Difference between Series protostomia and Series Deuterostomia is described below with the help of a table to understand the actual difference.

|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.|
