Amphibians live underwater and breathe through gills at one stage of their life and live on land breathing through lungs at a later stage.
Amphibians breathe through on land. Although they are not born with these organs they develop them during the metamorphosis they undergo during maturation. Amphibians are animals that can live on land or in water and they are characterized by moist glandular skin gills and a lack of scales. While adult amphibians spend part of their time on land they still need to.
On the other hand the adults can live and breathe both on land and underwater for part of the time. They also must be in moist environments to lay their eggs. They lay eggs in water not on land and their eggs are soft with no hard shell.
As weve already learned amphibians are very different from reptiles. Most amphibians reproduce in fresh water while a few lay their eggs on land and have developed mechanisms to keep the eggs moist. Their larvae not yet fully developed offspring mature in water and breathe through gills like fish while adults breathe air through lungs and skin.
They are animals of external or internal fertilization and oviparous. Reptiles have skin covered with scales breathe air through lungs and lay hard-shelled eggs on land. They have young that breathe through gills in water.
Yet they do not drink but absorb water through their skin. An example of an amphibian is this toad. With some amphibians it appears that they can breathe underwater when in fact they are holding their breath.
Egg Are Fertilized Outside of the Body. Some amphibians stow away in cracks in logs or between rocks during the winter. Amphibians on land primarily breathe through their lungs.
