Thermoregulation and water conservation of giant waxy monkey tree frog

They have shown to be able modulate their body temperature through control of evaporative water loss. As in other species in the family of leaf frogs, it has physiological and behavioral adaptations to limit water loss, reducing it through the skin by lipid secretions and excretion of uric acid (uricotelism), as well as entering diurnal torpor. Lipid secretions are produced in a special type of cutaneous gland which is densely packed along the entire surface of the frogs body.
