Adult amphibians breathe through lungs and moist skin
Young amphibians spend their lives entirely in water and breathe through gills. When they reach adulthood, they would have lost their gills breathe through lungs on land and through their moist skin in water!
Amphibians lay eggs
Amphibians lay eggs that are covered in a soft, jelly-like substance. They lay many eggs at once to increase the chances of some eggs hatching and some young surviving to reach adulthood to reproduce!
