Yes, frogs are known as amphibians. Humans are known as mammals.
Some frogs live in water and humans live on land. We do not have all the parts that a frog does. The parts that are similar are much smaller in a frog. Frogs have muscles in their legs that help them jump far and high, unlike us. Frog's lay eggs and humans don't. The frog's eggs can be scattered in the frog's body covering many organs. (in a female frog only) Speech, emotion and opposable thumbs are sadly lacking in frogs.
