Animals that live in the Australian desert must overcome the heat and find water and food to survive. Red kangaroos and emus have specific adaptations and behaviours enabling them to live in these conditions.
The freshwater crocodile has barely changed for 50 million years and has the greatest capacity to conserve energy. It can survive for two years without feeding.
During the clip students should list the physiological and behavioural adaptations of the kangaroo, emu and the crocodile. Students could choose another species that lives in a hot climate and compare their adaptations to those shown in the clip. The concept of convergent evolution could be discussed in which unrelated species may develop similar features to meet similar needs.
