Hi, that sounds like the group called Amphibians. This group includes frogs, most of which start out life as tadpoles that swim in water. As they get older they lose their tails and grow arms and legs. Then they can live on land, although they usually don't get too far away from water.

Yes, the standard definition of an amphibian is a vertebrate animal that lives part of its life (usually the developmental/childhood portion) in water and part of its life (usually the adult portion) on land. However, this isn't always a clear distinction - many amphibians such as frogs will spend their whole lives around and in water, but gain the ability to stay on land as an adult.
