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).
True crabs and centipeds
Two other phyla that a mouse belongs to are Chordata (which includes all vertebrates) and Arthropoda (which includes insects and spiders).
Hold your dick !
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.

Cnidaria and Ctenophora are the two phyla that are diploblastic, meaning they have two germ layers during embryonic development – the ectoderm and endoderm.
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.
The uniramia subpyhlum was divided into three phyla groups. These groups include insects, which is the hexapoda group, the myriapoda group of millipedes and centipedes, and the onychophora group of velvet worms
The two phyla of animals that contain an exoskeleton are Arthropoda, which includes insects, spiders, and crustaceans, and Mollusca, which includes animals like snails and clams.
The answer is probably sponges.
