Answer 2

Answer:

Phylum Porifera are the lowest multicellular animals belonging to the kingdom Animalia. ... Poriferans are pore-bearing first multicellular animals. The pores are known as Ostia. The poriferans have a spongy appearance and are therefore called sponges. They are attached to the substratum and do not move.
