Explanation
Phylum Porifera, which includes sponges, has no tissue level organization. Sponges are the simplest animals and are characterized by their lack of true tissues, organs, and body symmetry. Instead, they have a porous body with numerous openings called ostia, which allow water to flow through the sponge and filter out food particles.
