Amphibians are tricky. Some - like frogs and toads - start out using gills when they're tadpoles and switch over to lungs as they mature. There's a salamander that has the option to choose depending on water level whether to keep the gills or to develop lungs as it matures.
Some are so good at absorbing oxygen through their skin that they can stay submerged indefinitely even without gills.
it isn't an "or" question its just that amphibians have both lungs and gills.
It depends which kind of amphibian and sometimes they have both
they must have both, depending on how much land and how much water they will be dealing with.
When an amphibian is a larva, it will have gills. As it matures into the adult stage, it will develop lungs.
A amphibian has neither lungs or gills
Amphibian lungs do not have to be as efficient as gills because there is much more oxygen in air than in water.
Most amphibians grow out of their gills before adulthood.
Frogs and toads have gills as tadpoles, and lungs as adults.
gills, lungs, and permeable skin
They have four: Gills, lungs, tongue, and skin.
lung, skin and gills. by dinesh singh bhadouria
Many frogs and salamanders start their lives with gills, but when they grow they develop lungs.
They grow lungs, and lose their gills.
In the early stages of development, amphibians live in the water they breathe with gills as an adult an amphibian lives on land and uses lungs to breathe.
no because adult amphibians is breathe from lungs and young amphibian breathe through gills by:magno,jhon christopher
