- List and diagnose the families of modern crocodilians and describe the general distribution and habits of each.
- Discuss the most important changes that occurred in the evolution from dinosaur to Achaeopterix to modern bird.
- Describe and illustrate how air circulates through a bird's lungs and air sacs as it inhales and exhales and summarize the features that make bird respiration so very efficient.
