Just think of the complex system as a network of straws helping the lizard to get a drink. These tubes funnel water across the body and into the corners of the lizard's mouth, where it is then swallowed.
#Does skin absorb water skin#
Using high-powered microscopes to examine the skin and scales of the lizards, researchers found that two species, the Australian horny devil and the Texas horned, have networks of tiny tube-like channels beneath their scales, which cover their entire body. Patients with diseases like psoriasis and atopic dermatitis have. Conclusions: Heating the skin increases the rate of percutaneous penetration of water, while freezing does not alter the absorption of water. They hypothesized that the lizards were somehow using gravity to channel the water down towards their mouths. When the occasional ingredient is absorbed by your body through the skins protective barrier, your body generally can filter it out (thats wee). Results: Both percutaneous absorption of water and transepidermal water loss (TEWL) rates increase when the stratum corneum is damaged.
This perplexed researchers, prompting a study in which they began to notice that when the lizards got wet, they would raise their bodies and lower their heads.
However, unlike an amphibian's moist skin, dry lizard skin is designed to both keep water in and out. Scientists have always suspected that lizards absorb water much like their amphibious neighbors. The goal is to create products that work on the skin’s surface, not to absorb into your blood, as Robinson puts it. This does not make them any better at skin care. The bioplastic may absorb some of the water, but the bioplastic will remain largely stable (physically and chemically), and no breakdown will occur. Submerging bioplastics in a vat of water won’t do anything to the organic monomers. While some animals have developed ways of extracting water from the food they eat, or reducing water lost through evaporation, desert dwelling lizards don't drink water at all they absorb it through their skin. To achieve this feat of absorption, molecules need to be very small, oil-soluble (to break through the skin barrier), and water-soluble (to break through the blood barrier). That’s something that you can’t get in any body of water, or even in one drum of water.
Ever wonder how animals adapt to the lack of water in the scorching desert?
