Animals are classified according to many factors the first group is broke down based on if they have a back bone. Then they are classified by cell types such as animal cells, plant cells and fungi.
One way to classify animals is by the presence or absence of a backbone. Animals with a spine are known as vertebrates, while animals without them are known as invertebrates.
Body parts such as shells, pouches, webbed feet and others are used to classify animals. These things can be used to determine where an animal lived and how it used its body to survive.
Animal phyla is how animals can be classified according to body plan. The four types of body plans are sac like, acoelomate, pseudocoelomate, and coelomate.
Body structure: Animals can be classified based on their body symmetry (such as radial or bilateral symmetry) and body features (like presence of a backbone). Reproduction: Animals can be grouped based on their mode of reproduction, whether they lay eggs, give birth to live young, or reproduce asexually. Habitat and behavior: Animals can also be classified based on their habitat (land, water, or air) and behavior patterns (for example, carnivores or herbivores).
Spiders are classified as animals because they belong to the kingdom Animalia. They are multicellular, heterotrophic organisms that possess specialized cells and tissues, as well as a defined body structure with distinct organ systems. Additionally, spiders exhibit characteristics such as mobility, growth, and reproduction that align with the defining features of animals.
Biologists classify animals by their body structure, the way their body structure develops, and by their DNA.
Animalia.
Animalia: Classified based on body structure, presence of a backbone, and method of reproduction. Plantae: Classified based on presence of cell walls, ability to photosynthesize, and reproductive structures. Fungi: Classified based on mode of nutrition (absorptive), type of reproductive structures, and cell wall composition. Protista: Classified based on cell type, mode of nutrition, and locomotion. Monera: Classified based on cell structure, presence of a nucleus, and method of reproduction.

Anatomy is about the structure of the body. Zoology is about practically everything related to animals, their internal structure and habits.
Typically, the science of the structure and parts of organisms.
Homologous.
The body's structure is provided by the skeletal system (skeleton), which includes bones, cartilage, and connecting tissues. The bones hold up the body and give it structure - without bones, higher animals would not be able to exist.
