All about Amphibians
Amphibians are animals that live part of their lives in water and part on land. Frogs, toads, newts and salamanders are all amphibians. Their skin is usually thin and moist, and they absorb oxygen through it as well as through their lungs.
Most amphibians hatch from eggs laid in water. A frog starts life as a tadpole with gills and a tail. Over several weeks, it grows legs, absorbs its tail and develops lungs, a process called metamorphosis.

Frequently asked questions about Amphibians
What is the difference between a frog and a toad?
Toads usually have drier, bumpier skin and shorter legs, and they spend more time on land. Frogs have smoother skin and are more often near water.
Why do amphibians need water?
Their eggs need water to develop, and their moist skin needs to stay wet to absorb oxygen and avoid drying out.
Are amphibians endangered?
Many amphibian species are at risk from disease, habitat loss and pollution, so they are an important conservation focus.
