1. Frogs: Frogs are the classic example of amphibians. They spend their early lives in water as tadpoles, breathing with gills. As they mature, they develop lungs and legs, allowing them to live on land.
2. Salamanders: Salamanders are another group of amphibians. They are often found near water and have smooth, moist skin. Some species live entirely in water, while others spend most of their time on land.
3. Caecilians: Caecilians are legless amphibians that resemble snakes or earthworms. They are found in tropical regions and spend their lives burrowing in the soil or mud, but they can swim as well.
