The frogs have mucus glands in their skin that secrete mucus. These mucus glands keep the frog's skin moist so that the diffusion of gases can occur. Oxygen diffuses into the frog's bloodstream and carbon dioxide diffuses out.
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)
Frogs have underdeveloped lungs, so they must have a moist skin so that oxygen can diffuse into their bodies. Their lungs do not function well enough to be used on their own.
yes, but they can also accomplish much respiration through their skin in highly aerated water.
Yes. Frogs have smooth skin which is slippery and delicate.
No African Dwarf Frogs do not shed there skin.

Lungs and moist skin.
frogs use their skin for their respiration (since it is filled with capillaries). For most amphibians, 90% of their respiration is done through their skin. Frogs can also breath through the lining in their mouth which also contains capillaries, so a large amount of gas exchange can take place there. Frogs are able to breath through a pair of lungs as well, though this is used as more of a back up.

Frogs are very easily dehydrated and need to keep their skin moist permanently. To support this the hydrophyle (waterbinding) mucus is sectreted.

Frog's produce a slimy substance called mucus, the mucus comes from glands in the frogs skin. The glands and mucus is extremely important to the survival of the frogs due to the respiration and hydration. Not all frogs are slimy though, some frogs have rough dry skin.

Through their skin. If kept moist frogs do quite well in this mode of respiration.
Yes. Frogs have smooth skin which is slippery and delicate.

Yes, frogs creates mucus because they have mucus glands and it serves as a protection for dehydration and it also facilitates for their respiration because frog breathe through their skin too.
