Study Notes
Animal Diversity
- Animal classification is based on anatomy, morphology, evolutionary history, embryological development, and genetic makeup
- Animals are eukaryotic, multicellular, heterotrophic, develop into motile creatures with fixed body plans
- Unique to the animal kingdom is differentiated tissues (e.g., nerve, muscle, connective)
- Most animals reproduce sexually, with similar developmental stages across the kingdom
Body Symmetry
- Most animals are bilaterally symmetrical (except those with radial symmetry)
- Asymmetrical animals have no symmetry
- Radial symmetry: body parts arranged around a central axis (e.g., top/bottom, no left/right)
- Bilateral symmetry: body can be divided into mirror images along a sagittal plane (e.g., left/right)
Germ Layers
- Most animals have germ layers that develop during gastrulation, differentiating into tissues/organs
- Diploblasts (e.g., radial symmetry): two layers (endoderm, ectoderm); non-living layer between
- Triploblasts (e.g., bilateral symmetry): three layers (endoderm, ectoderm, mesoderm)
Internal Body Cavity
- Triploblastic animals may develop a coelom (internal body cavity derived from mesoderm) or not
