Behaviour and Physiology of Crocodiles

Dr Ross Dwyer discusses how the world’s largest living reptile copes with challenges of living in the water, and hunting at the water’s edge.

Everyone knows what a crocodile looks like, that they can grow to enormous sizes, and that they sometimes eat people. However, few are aware that they are also devoted mothers, have complex social systems, that they are amazing navigators, and the surprising fact that that crocodiles are actually more closely related to birds than they are to lizards!

In this video we will explore how dedicated field studies are revealing fascinating insights into the secret lives of crocodiles. We discuss the behavioural and physiological traits that make crocodiles exquisitely attuned to life underwater, and how traits that are shared between crocodiles and birds can provide unique insights into that of a common archosaur ancestor (e.g. the dinosaurs) that are not available in the fossil record.
