Uptake of Water by the Lizard, Moloch horridus

  title={Uptake of Water by the Lizard, Moloch horridus},
  author={Peter J. Bentley and W. F. C. Blumer},
Moloch horridusis an agamid lizard living in the desert regions of Western and South Australia. It weighs as much as 50 gm. and has been described by Buxton1 as “a repulsive animal with tubercles and spines, it has the power of absorbing water through the skin after showers of rain”. This ability of absorbing water through the skin is characteristic of many Amphibia and is correlated with a ready loss of water by the same route2. Reptiles living in arid conditions would find a water-permeable… Expand
Rain-drinking behaviors of the Australian thorny devil (Sauria: Agamidae)
Circumstantial behavioral evidence, in combination with experimental studies, suggests that the capillary, interscalar, water-transport system of Moloch is also used to absorb water for drinking from rain-moistened substrates. Expand
Water collection by the body in a viperid snake, Bothrops moojeni
Rates of evaporative water loss did not differ between juvenile and adult snakes, but since juveniles have a greater surface-to-volume ratio, they were significantly more sensitive to desiccation than the adults. Expand
The Ecology of Moloch horridus (Lacertilia: Agamidae) in Western Australia
The ecology of Moloch is compared with that of its North American ecological analogue Phrynosoma platyrhinos, and there are a number of striking differences in their ecologies, which can be explained, in part, by the differences between the Australian and the American desert environments. Expand
Cutaneous water collection by a moisture-harvesting lizard, the thorny devil (Moloch horridus)
The results suggest that rain and moist sand seem to be ecologically likely water sources for M. horridus on a regular basis. Expand
Cutaneous Water Acquisition by the Thorny Devil (Moloch horridus: Agamidae)
The low permeability of the skin to evaporative water loss and lack of dyed water absorption suggest that there is not any transcutaneous water absorption across the skin itself. Expand
Adsorption and movement of water by skin of the Australian thorny devil (Agamidae: Moloch horridus)
Using micro-computed tomography and scanning electron microscopy of shed skin to investigate capillary morphology, it is found that the channels are hierarchically structured as a large channel between the scales that is sub-divided by protrusions into smaller sub-capillaries. Expand
Physiological , morphological and behavioural adaptations of the ultrapsammophilous , Namib Desert lizard
The biology of desert amphibians and reptiles has recently been reviewed at some length by Mayhcw (1968). He points oul that, although a considerable number of desert lizards have been studied, veryExpand
Cellular Dehydration as a Stimulus to Drinking in the Common Iguana, Iguana Iguana
Present-day reptiles range from the completely aquatic, for example the sea snakes and turtles, to the highly successful colonisers of the more arid regions of the world, which are well suited to terrestrial life by having a skin that is impermeable to water. Expand
Rain-Harvesting by the Southwestern Speckled Rattlesnake (Crotalus mitchellii pyrrhus)
My observations suggest that C. mitchellii may engage in rain-harvesting when thermal conditions are not optimal (i.e., during cold temperatures). Expand
Rain-Harvesting in the Lizard, Phrynosoma cornutum: Behavior and Integumental Morphology
This is the first report to provide observations of a lizard obtaining water from natural precipitation for drinking by integumental inter- ception and transport. Expand
