be restricted to smaller and/or thinner body plans.
The process by which an animal can breathe without lungs ie. through moist skin. Oxygen can pass through the skin into the blood capillaries close to the skin surface. Examples are amphibians, specifically the 'lungless salamanders'.
Almost all salamanders belong tot the Plethonidae-family: the so-called lungless salamanders. They don't have lungs but breathe completely throught their throats and their skin. You could say this is the major adaption of the salamanders. A disadvantage is that as soon as the salamander enters a dry area, it inmediately starts to dehydrate. Most salamanders can only survive in permanent moit environments. They may also Create a Larvae around their bodies to protect themselves from a some-what attack.

Frogs,toads,salamanders,leech
There are many different varieties of salamanders. Most of these salamanders have both gills, and lungs. There are also some that have gills, but then lose them as they get older. They then use lungs for breathing.
Gills for tadpoles, lungs for adults.Gills for tadpoles, lungs for adults.Adults have lungs, and the skin of the frog can absorb tiny amount of oxygen through their skin. Tadpoles have gills.The skin.the answer is the amphibian breathe through their gills, skin, and soon they use their lungs to breatheLarvae have gills, and adults have lungs.

Most frogs have lungs, but their are lungless frogs. They can also breath thru their skin.
Since frogs spend most of their lives in water there is a huge advantage to having a redundant system of getting oxygen. The need for a frog to be able to breathe without surfacing during the winter months makes "skin breathing" very advantageous. The use of lungs is effective when the frog is on the surface (especially when completely out of the water).
Salamanders breathe by gills, lungs, mouth lining, and skin, sometimes in combination, sometimes separately. Members of the water dwelling salamanders lack lungs and breathe through the skin and mouth.Salamanders have skin through which oxygen and carbon dioxide can enter and leave the body. Most adult salamanders also have lungs and use their skin only as a source of extra oxygen.I beleive they breathe through their skin through miniscule holes called "spiracles."by opening there mouth and saying "EAK"

some frogs breath through skin some don't.
