Young Amphibians Breathe With

Oxygen from the air or water can pass through the moist skin of amphibians to enter the blood.

Young amphibians breathe with. They are vertebrates and cold blooded like amphibians. With some amphibians it appears that they can breathe underwater when in fact they are holding their breath. As the tadpole grows the gills disappear and lungs grow though some amphibians retain gills for life.

How do amphibians breathe. Amphibians have evolved multiple ways of breathing. Amphibians breathe with gill.

Early in life amphibians have gills for breathing. However young amphibians breathe through gills. Tadpoles are frog larvae.

Amphibians have primitive lungs compared to reptiles birds or mammals. With the exception of a few frog species that lay eggs on land all amphibians begin life as completely aquatic larvae. One example of an amphibian is a frog.

The species in this group include frogs toads salamanders and. As compared to reptiles amphibians have smooth skin. Just like most amphibians the different salamander species breathe through a membrane in their throat and mouth skin lungs and gills.

These lungs are primitive and not as evolved as mammalian lungs. The gills lie behind and to the side of the mouth cavity and consist of fleshy filaments supported by the gill arches and filled with blood vessels which give gills a bright red colour. Their skin has to stay wet in order for them to absorb oxygen so they secrete mucous to keep their skin moist If they get too dry they cannot breathe and will die.
