Can someone please explain the different Animal Classifications to me? I'm doing biology and i'm really struggling with this area. My School textbook and lessons don't explain the subject very well. I just don't know what Phylum, Kingdom, Domain, Clade, Class, family (and i'm sure theres a few other classifications I left out) even mean or group. Also How does a Cladogram of animals work? I'm really struggling to understand this. Please help?

The classification system is a little complicated. The key is that the finer groups - like family and order - are subcategories of the bigger groups like phylum and class.
For example, you can classify all organisms into kingdoms. You would place all organisms that are plants in one kingdom, all organisms that are animals in another. If you then focused on just one of those groups - plants or animals - you can further subdivide it based on more complex traits. For example, if you focused on the plant kingdom, you could divide plants into two subgroups or 'phyla' based on whether they are flowers or grasses or trees.
Then you could focus on one of those phyla within the plant kingdom and further subdivide it into classes. For example, you could take the phylum "trees" and divide it into one class, which is leafy trees, and a second class which is pine trees or needled trees.
Hope that is helpful :)
