How does the thorny devil use capillary action?
Grooves on spikes of thorny devil lizard provide drinking water by drawing condensed dew to mouth by capillary action. The Thorny Devil (Moloch horridus) can gather all the water it needs directly from rain, standing water, or from soil moisture, against gravity without using energy or a pumping device.
How do thorny devil lizards adapt to the desert?
Moisture-harvesting lizards, such as the Australian thorny devil Moloch horridus, have remarkable adaptations for inhabiting arid regions. Their microstructured skin surface, with channels in between overlapping scales, enables them to collect water by capillarity and passively transport it to the mouth for ingestion.
What helps the thorny devil survive?
Adaptations. The thorny devil is diurnal (active during the day time). The spikes all over their bodies help them get a drink of water in the dry sand country. In the mornings they rub up against dew drops on the spinifex and the moisture runs between the spikes along grooves that run directly into their mouths.

Do thorny devils drink through their skin?
A team of researchers with Aachen University in Germany has found that the thorny devil lizard is able to supplement its water intake by covering its body with sand and then using straw-like folds in its skin to pull in water, which is then directed to its throat.
How do thorny devil get water?
The thorny devil stays hydrated thanks to its skin, which pulls water away from moist grains, against gravity and into its mouth.
Do thorny devils have adaptations?
Moisture-harvesting lizards, such as the Australian thorny devil Moloch horridus, have remarkable adaptations for inhabiting arid regions. Their microstructured skin surface, with channels in between overlapping scales, enables them to collect water by capillarity and passively transport it to the mouth for ingestion.
What do horny toads eat?
Phrynosoma douglassi
