-Flexible cell membranes
-No chloroplasts
Organ systems are not present in all animal phyla.
Phyla are determined by major anatomical features. Does the organism have a spine? Is there a skeleton, and if so is it internal or external? Does it have a shell? Is it motile or sessile? Does it conduct photosynthesis? How many limbs does it have? Does it have hair? Does it have feathers? Does it have eyes? And so forth.

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.

There are four major phyla's of animal-like protists. These four are sarcodina, ciliophora, sporozoa, mastigophora. With ciliophora being the main one.

Phylum
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.
