Question

name two animals having cutaneous respiration. what special features of the skin make cutaneous respiration effective?

Answer 1

Cutaneous respiration is a form of respiration in which gas exchange occurs across the skin rather than the lungs or gills. They occur in many organisms like insects, amphibians, fish, sea snakes, turtles and few mammals too. The skin of such organisms is very special that they are used for breathing. In order to breathe through the skin, it has to be moist for oxygen and carbon dioxide to pass through.

Certain amphibians have a lot of folds in their skin in order to increase the rate of respiration. Frogs are known to drink water and breathe through their skin. They have three ways of breathing – through their skin, lungs and lining of the mouth. While at rest, breathing via the mouth becomes predominate form of breathing.
