Also question is, do frogs have gills or lungs?
Frogs, like salamanders, newts and toads, are amphibians. Most amphibians begin their life cycles as water-dwelling animals, complete with gills for breathing underwater. As they grow to adulthood, amphibians normally become land-dwelling creatures, lose their gills and develop lungs for breathing.
Likewise, do amphibians breathe air or water? Yes, they can. Oxygen from the air or water can pass through the moist skin of amphibians to enter the blood. Many young amphibians also have feathery gills to extract oxygen from water, but later lose these and develop lungs.
Similarly, you may ask, do reptiles have gills or lungs?
Reptiles are born in eggs on land and amphibians are born in eggs in the water. And because amphibians are born in water they have gills when they are young, whereas reptiles have lungs. In fact, amphibians are a lot like fish when they are first born, but when they grow, they become more like reptiles.
Do salamanders have gills and lungs?
Some species that lack lungs respire through gills. In most cases, these are external gills, visible as tufts on either side of the head. Some terrestrial salamanders have lungs used in respiration, although these are simple and sac-like, unlike the more complex organs found in mammals.
