Which animal take breathes through skin?

Question

Which animal has very low metabolic rates and a quarter of the muscle tissue of animals of similar size, and whose hair grows in a direction opposite to that of its extremities?

Answer 1

Frog take breathes through their skin. An adult bullfrog use their skin for 80% breathing. The main disadvantage of breathing through the skin is that the animal loses a lot of water in this way. The skin of these animals is always wet. To stop their bodies from drying out they must always live where the air is humid.
