developing an empirical argument that describes the intimate connections between …

A carrier system for gases and nutrients became mandatory when primitive animals grew
larger and developed different organs. The first circulatory systems are peristaltic tubes …

Constricting pythons, known for their ability to consume infrequent, massive meals, exhibit

Snakes and lizards are considered 'stoic'animals and often show only non‐specific signs of

Many types of snakes are capable of surviving over a year of complete starvation. The
physiological effects of food limitation on snakes can be appreciated both by controlled …

Pythons are renowned for a rapid and pronounced postprandial growth of the heart that
coincides with a several-fold elevation of cardiac output that lasts for several days. Here we …
