Expert Answer:

Cutaneous respiration is the respiration or gas exchange carried through skin.

in some vertebrates the body surface has become highly vascularized for gaseous exchange. Such exchange is of particular importance in the class Amphibia, where mucous glands in the skin maintain a moist respiratory surface; and in the soft-shelled turtles.

Frog skin has mucous producing glands that help keep it moist. Frogs also depends on cutaneous respiration for their oxygen supply. In this method of respiration, oxygen from the air is drawn into a frog's body by the blood vessels that lie close to the skin. Waste gas and carbon dioxide are also released the same way. In order for all the transfer to take place, frog's skin must be moist.
