Two features defining the animal phyla are adult body plans and patterns of embryological development.
An exoskeleton is an external skeleton that protects and supports the animal's body. Two phyla that have exoskeletons are Arthropoda and Heterokontophyta.
Arachnids and Platyhelminthes are two types of animal phyla even though there are many more.
Most animal phyla exhibit bilateral symmetry, where the body can be divided into two mirror-image halves along a single plane. This body plan is thought to have evolved for efficient movement and coordination in organisms.
The two animal phyla that show radial symmetry are Cnidaria (such as jellyfish and sea anemones) and Echinodermata (such as starfish and sea urchins). Radial symmetry means that the body parts are arranged symmetrically around a central axis, like spokes on a wheel.
Cnidaria and Ctenophora are the two phyla that are diploblastic, meaning they have two germ layers during embryonic development – the ectoderm and endoderm.
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.

actually seven of the 9 phyla use extracellular digestion. the two that are intracellular are porifera and placozoa

Two other phyla that a mouse belongs to are Chordata (which includes all vertebrates) and Arthropoda (which includes insects and spiders).

The answer is probably sponges.
