Question

Why are sponges considered as Parazoa​

Answer 1

Answer:

The correct answer is:

Sponge phyla have few traits in common with other metazoan phyla. They appear to be on the other side of the evolutionary tree that leads from choanoflagellates to other metazoa. As a result, they are frequently referred to as Parazoa.

Explanation:

• The phyla Porifera and Placozoa are both included in the animal sub-kingdom Parazoa.
• The most well-known parazoa are sponges.
• They are aquatic animals that belong to the phylum Porifera, and there are over 15,000 species worldwide.
• Although sponges are multicellular, they only have a few different types of cells, some of which migrate throughout the organism to serve various activities.
