Temperature Regulation

The Water Holding Frog (Cyclorana platycephalus) and the Greater Bilby (Macrotis lagotis) exhibit remarkable adaptations for regulating body temperature in extreme environments. The Water Holding Frog burrows into clay to insulate against temperature changes and enters dormancy to reduce heat production while absorbing moisture from the surrounding soil. The nocturnal Greater Bilby uses its large ears to radiate heat and seeks refuge underground during the scorching day. These survival strategies are crucial for their existence in harsh Australian climates.

Presentation Transcript

  1. Temperature Regulation The Water Holding Frog The Greater Bilby

  2. The Water Holding Frog Scientific Name: CycloranaPlatycephalus

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

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

  5. Absorbing water from surrounding soil helps maintain a low body temperature.

  6. The Greater Bilby Scientific Name: Macrotislagotis

  7. Large ears help to radiate heat

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

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