The Water Holding Frog

Scientific Name:

Cyclorana Platycephalus

By burrowing into the clay, the frog is able to insulate itself from temperature changes

By becoming dormant, the water-holding frog is able to minimize heat production.

Absorbing water from surrounding soil helps maintain a low body

temperature.

The Greater Bilby

Scientific Name:

Macrotis lagotis

Large ears help to radiate heat

As a nocturnal animal, the bilby is able to avoid the extreme day-time temperatures.

Burrowing into the soil allows the bilby to escape the heat above ground.
