Ways tadpoles are different from frogs

Frogs have legs, tadpoles don't.

Tadpoles live only in water, frogs live in the land and water.

Frogs are larger than tadpoles.

Tadpoles are basically baby frogs.

A tadpole has a tail. A tadpole is a young frog. (A frog is older, a tadpole is younger.) A tadpole lives mainly in the water and frogs can stay out of water for some time. Tadpoles may have different coloring. Tadpoles don't croak or peep. (I think.) Tadpoles look different overall.
