Deuterostomes
‘Deutero’ means second and ‘stomes’ means mouth. This means that Deuterostomes are the animals in which Blastopore forms the anus first and then the mouth. In Deuterostomes, a hollow nerve cord is present. They exhibit indeterminate and radial cleavage.
Deuterostomes Examples
Deuterostomes includes Echinodermata, Hemichordata, and Chordata.
- Echinodermata – Starfish, sea urchins, and sea cucumbers
- Hemichordata -acorn worms, graptolithina
- Chordata – Humans, fish, mammals
Difference Between Protostomes and Deuterostomes
The key difference between Protostomes and Deuterostomes lies in the development of their embryonic cells, with protostomes forming the mouth first during embryogenesis, while deuterostomes develop the anus first. Protostomes and Deuterostomes are two types of organisms with tubes within a tube body plan
The major difference between these two is based on the fate of Blastopore. In this article, we will cover the difference between Protostomes and Deuterostomes.
