In this specific podcast, I will dissect a speaking Part IV audio and then record one for everyone to submit to me. Recently, I had a guy from Egypt share his TOEFL recording with me (and it should be coming out in podcast for very soon if it hasn’t already) and I went over the good points and areas that need improvement. So, I want to make this a challenge to everyone and do it yet again!

Desert frogs have developed ways of adapting to hot and dry climates. Those adaptations to aridity that evolved during dry seasons have helped frogs survive the inevitable droughts. One evolutionary adaptation that a frog uses to survive severedry climates is to retain and store water in their bladder. Because of a frog’s highly flexible bladder, during most seasons, frogs are able to store a substantial amount of water inside their bladder. Therefore, during dry seasons, frogs release the water from their bladders to keep their bodies moist and their organs functioning properly. Another evolutionary adaptation the desert frog has to survive droughts is a fatty layer below their skin. This fatty layer, in addition to the stored water like the frog’s bladder, also helps reduce water evaporation during those extremely hot seasons. Ultimately, the desert frog has adapted to hot climates by evolving unique methods of storing substantial amounts of water, which the frog retains for an extended period of time and subsists on during these droughts.
