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.
I think the leech has Bilateral symmetry meaning that if you cut it down the middle you will get two mirror images.
The answer is probably sponges.
The phylum Arthropoda is not one of the major phyla of animallike protists. Arthropoda belongs to the animal kingdom and includes insects, spiders, and crustaceans, while animallike protists are members of the protist kingdom.

Arthropoda and Heterokontophyta
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).
They belong to the phyla Platyhelminthes, along with the flatworms. Members in this phyla are acoelomates.
porifera
this is stupid
asconoid sponges, and syconoid
Cnidaria and Ctenophora are the two phyla that are diploblastic, meaning they have two germ layers during embryonic development – the ectoderm and endoderm.
sea star and ocean fish star
Porifera (sponges) have no specialized cells. To be diploblastic animal phyla must have a minimum of two cell layers referred to as ectoderm and endoderm. The absence of these cell types make it impossible for any members of porifera to be diploblastic.

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.
An exoskeleton is an external skeleton that protects and supports the animal's body. Two phyla that have exoskeletons are Arthropoda and Heterokontophyta.
