• Amphibians


  • Are cold-blooded
  • Have soft, moist skin that can absorb water and oxygen
  • Breathe through their lungs
  • Live both on land and in water
• Amphibian life cycle


  1. Hatch from eggs laid in water as tadpoles

  2. Tadpoles have gills to breathe in water

  3. As they grow, tadpoles develop lungs and start living on land

  4. Return to water to reproduce
• Amphibians


  • Frog
• Fishes


  • Are water-living vertebrates
  • Have gills to get oxygen from water
  • Have fins to help them move through water
  • Are cold-blooded
  • Have bodies covered with scales
  • Reproduce by laying soft or jelly-coated eggs
• Fishes have adaptations for living and moving in water, including a streamlined shape to reduce friction, silver coloring for camouflage, and gills with a large surface area to extract oxygen from water
