Amphibians

  1. 2. Frogs toads salamander
  2. 3. Did you know that wood frogs during winter freezes and then thaws back to life? - Breathing, heart beat, and muscle movements all stop and the frozen "frog-sicle" exists in a virtual state of suspended animation until it thaws .
  3. 4. Class Amphibia is represented by animals that can live in water as well as on land. The name of the class came from the Greek words “amphis” (double) and “bios” (life). Thus, the word amphibian means double life: one life on water and on land.
  4. 9. These hatch into tadpoles that breathe through their gills. As they grow, they lose their tails and develop their legs for successful life on land.
  5. 10. Amphibians need to live close to water to prevent their skins from drying up. They keep their skin moist to with stand dry conditions on land and to supplement breathing through primitive lungs .
  6. 11. Frogs lay hundreds of eggs. The tadpoles feed on small pond animals. Soon their fins begin to disappear and the start to look like adult frogs. They begin to breath through their lungs instead of through their skin. Adult frogs spend most of the time in water. Nostrils are found on top of frogs’ head so they can breathe while submerged in water.
