Frogs and Toads Frogs and toads are one of the most common species of amphibians.
They are found not only in the wetlands, but all over the world. The
young go through a larval stage in the water. During these stages
they lose their gills and grow webbed feet. Much of their
reproductive qualities vary with respect to their specific species.
Frogs often consume insects and lay eggs to produce young.
Do you know the difference between amphibians and reptiles? Look
at the chart below to compare:
| Amphibians |
Reptiles |
- Moist, thin skin
- Limbs, if present, often webbed; no claws
- Respiration by gills, lungs or skin
- Heart 2-chambered in immature; 3-chambered in adult
- External fertilization
- Eggs generally laid in water
- Metamorphosis from aquatic larval form to adult
|
- Dry scales cover skin
- Limbs, if present, with claws on toes
- Lung breathing
- Divided heart ventricle
- Internal fertilization
- Amniote eggs laid on land (free from dependency on water)
- Some give live birth (ex. garter snake)
- Yound look like adult (no metamorphosis)
