Cutonivious respiration
This process of molecular exchange is called transpiration.

by skin
Amphibians
your skin is the most important stage of cellular respiration
If an amphibian's skin dries up, it can have difficulty breathing, absorbing water, and regulating its body temperature. This can lead to dehydration and put the amphibian's health at risk. Skin plays an important role in respiration and hydration for amphibians.
A frog is an amphibian, but adult frogs do not have gills. They absorb oxygen from the water through their skins, using special blood vessels. If the oxygen level in water is too low, frogs will move around to increase the water flow across the skin. Some frogs have creased skins that can increase their surface area. (see related question)
their large surface areas of moist skin, have no any specific organ for respiration.
Respiration in the earthworm is fairly simple. The earthworm has moist skin and it respires through the skin surface by taking in oxygen and giving out carbon di-oxide.
In animals that rely on skin for respiration, the skin must be moist. This moisture helps facilitate gas exchange by allowing oxygen and carbon dioxide to diffuse through the skin. Dry skin would impede this process.
Skin plays a minor role in respiration by allowing a small amount of gas exchange to occur through diffusion. However, the majority of oxygen and carbon dioxide exchange in humans occurs through the respiratory system, specifically in the lungs. The skin is not the primary organ involved in respiration.
Respiration of animals in the Phylum Vertebrata, Class Amphibia, including classes such as urodela, anurans, & apodans. It involves respiration through the skin.
