∙ 12y agoThe two main differences between a sponge and a roundworm is that a sponge has asymmetrical body plan, a roundworm has bilateral symmetry. The other difference is that a sponge lives in the ocean, roundworms live in freshwater habitats, in damp soils and as parasites in the tissue and body fluids of other animals.

∙ 14y agoFirst of, they are in two different phylum. Flat worms are in the planarian phylum while, Porifera is the sponges phylum. Sponge has no organs, and can reproduce asexually. Many flat worms are parasites while no sponges are. Another thing is sponges have no symmetry while flat worms have bilateral symmetry. Hmmm what else... on yes flat worms have one body opening while, i not 100% sure sponges have two.
