..., or absorption from moist sand, and we evaluate here the potential of these various sources for water uptake by M. horridus . The water volume required to fill the skin capillary system is 3.19% of body mass. Thorny devils standing in water can fill their capillary system and then drink from this water...

... homeostasis reabsorption water uptake Renal mechanisms controlling ionic and fluid homeostasis in insects make use of the functional unit of the Malpighian tubules (MTs) and the hindgut. Excretion begins by primary urine formation from osmotically obliged water via ion and solute secretion...

... mosmol kg -1 H 2 O. Water uptake diminished under mannitol acclimation while the apparent osmotic permeability under NaCl and urea acclimation increased. Urea and sodium influx across the isolated skin changed inversely upon hyperosmotic acclimation, but they did not seem to depend on one another...
