Amphibians Class
Fun Facts:
- Skin: An amphibian's skin is permeable, meaning it can absorb water and oxygen directly through it. This is why they must live in damp environments to avoid drying out.
- Lungs: Even after developing lungs, many amphibians continue to get a significant amount of their oxygen through their skin.
- Life Cycle: The change from a gilled, water-dwelling tadpole to a lung-breathing, land-dwelling frog is a complete rebuilding of the body called metamorphosis.
- Structure: They have smooth, moist skin with no scales, fur, or feathers. They typically start life with gills and later develop lungs. Many, like frogs, have powerful hind legs for jumping.
