1. The Tasmanian Devil (Sarcophilus Harrisii) Endotherm The Tasmanian devil’s habitat is considered to be within the low to moderate annual rainfall zone of Eastern and North Western Tasmania. They like dry sclerophyll forests and coastal woodlands.

2. They are often found beside roads where road kill is prevalent but this also causes a lot of deaths. Extremely loud and disturbing screech Keen sense of smell and ferocity when eating Its large head and thick neck allow it to generate the strongest bite per unit of body mass of any mammal land predator

3. Being an endotherm the Devils body metabolism generates heat and maintains an internal body temperature that is independent of the external temperature. The Devils very efficient metabolism allows it to keep warm in the harsh Tasmanian cold climate, but able to prevent over heating on hot days. With a spike in the temperature and humidity the Tasmanian devil is efficient at regulating its body temperature; they do this by drinking more water and by panting to release body heat.

4. They will also seek cold shade and lie out stretched to increase their surface area for maximum cooling effect. They use wombat holes as their dens and huddling up with their young to keep warm. The sun provides good warmth through radiation, which is readily absorbed by their dark fur.

5. The devil is able to maintain a stable body temperature from temperatures that are cool at night to the middle of the day. The Tasmanian devil has adapted to its natural environment and human environment to assist with its temperature regulation for optimal metabolism.

6. The Australian Green Tree Frog (Litoria Caerulea) Ectotherm MALEFEMALE

7. The Green Tree Frog has large disc like structures on the ends of their fingers and toes to assist climbing. They also have some webbing on their feet to assist swimming. The Green Tree Frog is distributed through the eastern and northern parts of Australia where it is more temperate. It prefers cool damp places, and particularly in more arid areas the frog with use human habitation for shelter (downpipes, tanks and guttering

8. Rely on the environment to regulate body temperature They generate heat chemically and internally by breaking down food The frogs body reflects the air and water temperatures around them They move around the environment to regulate their body heat The frog will produce heat through conduction radiation Conduction is from the warm rocks and radiation of heat from the sun Is the frogs warm up they will then move to cooler moist areas to cool down

9. The frog as an ectotherm relies heavily on its adaptations to temperature regulation to survive in its wild environments.
