5. Difficulties

   • This difficulty in philosophically regulating body temperature means that certain behaviors are present in amphibians, aimed at improving their quality of life, and compensating for the deficiencies in their bare skin, which is very susceptible to cooling or dryness if they do not have adequate hydration; For this reason, most amphibians are nocturnal and register activity in those environments that have sufficient humidity.
   • Amphibians have big difficulties by moving from the water on to the land.
