Here's the breakdown of the classification:

* Domain: Eukarya (organisms with cells that have a nucleus)

* Kingdom: Animalia (multicellular, heterotrophic organisms that obtain nutrients by consuming other organisms)

* Phylum: This is where it gets more specific! There are many different phyla within the Animalia kingdom, such as Chordata (animals with a backbone), Arthropoda (insects, spiders, etc.), Mollusca (snails, clams, etc.), and more.

* Class: This level further divides the phyla. For example, within the phylum Chordata, there are classes like Mammalia (mammals), Aves (birds), Reptilia (reptiles), Amphibia (amphibians), and Fish (fish).

So, while Animalia is the class for all animals, it's important to remember that this is a very broad category. You'll need to consider the specific animal in question to determine its phylum and class.
