•They like dry sclerophyll forests
and coastal woodlands.
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 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
•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.
•Being an endotherm the Devils body metabolism
generates heat and maintains an internal body
temperature that is independent of the external
temperature.
•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.
•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.
•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.
The Australian Green Tree
Frog
(Litoria Caerulea)
Ectotherm
MALE
FEMALE
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
Rely on the environment to
regulate body temperature
Is the frogs warm up they
will then move to cooler
moist areas to cool down
They generate heat chemically
and internally by breaking down
food
They move around the
environment to regulate their
body heat
Conduction is from the
warm rocks and
radiation of heat from
the sun
The frog will produce
heat through conduction
radiation
The frogs body reflects the air and
water temperatures around them
The frog as an ectotherm relies heavily on its adaptations
to temperature regulation to survive in its wild
environments.
