Crocodilia
- The myodural bridge of the American alligator (Alligator mississippiensis) alters CSF flow
Summary: Skeletal muscle contraction alters circulation of the cerebrospinal fluid.
- The respiratory mechanics of the yacare caiman (Caiman yacare)
Summary: The respiratory system of the caiman stiffens during development. Most of the work of breathing overcomes elastic forces and increases during submergence. Flow resistance plays a significant role at higher ventilation frequencies.
