Ck 12: Life Science: Amphibians

[Free Registration/Login may be required to access all resource tools.] Amphibians are a group of vertebrates that have adapted to live in both water and on land. Amphibian larvae are born and live in water, and they breathe using gills. The adults live on land for part of the time and breathe both through their skin and with their lungs.
