What are some common features of animals?

Common features of animals are organs, such as the eyes, heart, brain, stomach, intestines, lungs, etc. Most animals have limbs, but not all, so that technically isn't counted as a "common feature". Animals all have these same features: -No chloroplasts in their cells

-They are multicellular eukaryotes with cells with different functions forming tissues

-They do not have cell walls

-They can have cilia or flagella

-They feed heterotrophically (they do not make their own food but eat other things for their energy.)
