In the lecture, the professor talks about two dry-climate features of frogs. Some frogs prevent water loss by creating a covering over their skin. The covering can reduce the exposure of frogs’ skin to the dry air and lock in moisture. For example, some frogs secret a fatty substance and create a waxy watertight layer that wrap up all their bodies. Other frogs maintain moisture by keeping water in an internal organ that can absorb and store much rainwater to get through dry periods. For example, some water-holding frogs have stretchable bladders to absorb and hold water when it rains, and then release water into other internal tissues until the next rain.
