Answer 2

Answer:

The sponges and sea star or starfish belong to different phylum though they have some common features between them, one of which is the calcareous protective material.

Sponges belong to the phylum, Echinodermata whereas sea stars belong to the phylum, Porifera.

Porifera are named so specifically because of the presence of pores in their bodies. On the other hand, sea stars are star-shaped organisms which are mainly present on the sea bed of oceans.
