What is the Difference Between Porifera and Coelenterata?

Porifera and Coelenterata are two primitive animal phyla belonging to the kingdom Animalia. The main differences between them are:

1. Body organization: Porifera animals show cellular level organization, while Coelenterata animals have a tissue level of organization.
2. Mobility: Porifera animals are non-motile, while Coelenterata animals are capable of locomotion.
3. Body cavity: Porifera animals have numerous pores or holes all over their body, while Coelenterata animals have a body cavity with a single opening.
4. Skeletal structure: Porifera animals possess an exoskeleton, while Coelenterata animals do not have an exoskeleton.
5. Mesohyl and Mesoglea: In Porifera animals, Mesohyl is found between the two cell layers, while in Coelenterata animals, Mesoglea is found between the two cell layers.
6. Symmetry: Porifera animals are asymmetrical, while Coelenterata animals show radial symmetry.
7. Nervous system and organs: Porifera animals do not have organs or nerve cells, while Coelenterata animals possess a simple nervous system and simple organs.

In summary, Porifera and Coelenterata are two different phyla of primitive aquatic animals, with Porifera being non-motile and having a cellular level of organization, and Coelenterata being capable of locomotion and having a tissue level of organization.

Comparative Table: Porifera vs Coelenterata

Here is a table that highlights the differences between Porifera and Coelenterata:

Porifera, also known as sponges, are marine animals with a cellular level of organization. They are non-motile and possess many pores in their bodies. The phylum Coelenterata, on the other hand, includes radially symmetrical aquatic animals with a simple tissue level of organization. These animals are motile and have a single opening in their coelenteron.
