platyhelminthes
this is stupid
asconoid sponges, and syconoid
Two other phyla members of a roundworm are Nematoda and Nematomorpha. They are both non-segmented worms that belong to the superphylum Ecdysozoa along with roundworms (phylum Rotifera).
sea star and ocean fish star
They belong to the phyla Platyhelminthes, along with the flatworms. Members in this phyla are acoelomates.
porifera
Tapeworms belong to the phylum Platyhelminthes, which is also home to other members such as planarians and flukes. Planarians are free-living flatworms known for their regenerative abilities, while flukes are parasitic flatworms that can infect various hosts, including humans. Both groups share characteristics of flat body structures and bilateral symmetry, common to the phylum.
Sponge phyla primarily include Porifera, which contains various classes and species of sponges. Other members of the animal kingdom that are related to sponges, albeit not within the same phylum, include members of phyla such as Cnidaria, which includes jellyfish and corals, and Ctenophora, known as comb jellies. Both of these phyla share some primitive characteristics with sponges but are distinct groups with their own unique features.
Arthropoda and Heterokontophyta
There are more than two phyla in the animal kingdom... There are many phyla in the animal kingdom. There are a few phyla of worms and other invertebrates and then you have the vertebrate ohyla. Unless that's what your asking? Did you want the invertebrate and vertebrate in general phyla? That's the only set of 2 things I can think of.
Some common parasitic members of the phyla that infect humans include Platyhelminthes (flatworms) like tapeworms and flukes, Nematoda (roundworms) such as hookworms and pinworms, and Arthropoda (arthropods) like mosquitoes and ticks which transmit diseases.
