Study Notes
Kingdoms
- Highest taxonomic rank in animal classification
- 6 main kingdoms: Animalia, Plantae, Fungi, Protista, Archaea, and Bacteria
- Characteristics used to distinguish kingdoms:
- Cell structure (eukaryotic or prokaryotic)
- Cell wall composition
- Mode of nutrition
- Body organization
Phyla (or Divisions)
- Level below kingdoms
- 30-40 phyla in the kingdom Animalia
- Characteristics used to distinguish phyla:
- Body structure (e.g., radial or bilateral symmetry)
- Number of cell layers
- Presence of coelom (body cavity)
- Type of appendages
Classes
- Level below phyla
- Characteristics used to distinguish classes:
- Body structure (e.g., skeletal system, skin)
- Type of digestive system
- Respiratory system
- Reproductive system
Orders
- Level below classes
- Characteristics used to distinguish orders:
- Limb structure
- Dental structure
- Type of feathers or scales
- Brain structure
Family
- Level below orders
- Characteristics used to distinguish families:
- Shared physical characteristics
- Similarities in behavior
- Genetic similarities
Genus
- Level below family
- Characteristics used to distinguish genera:
- Closely related species
- Shared physical characteristics
- Genetic similarities
Species
- Most specific taxonomic rank
- Characteristics used to distinguish species:
- Reproductive isolation
- Unique physical characteristics
- Genetic differences
- Ecological niche
