A friend tells you that a frog and a fish belong to the same group because they both live in a pond. Do you agree or disagree? Explain why.
I disagree. Frogs are amphibians, not fish. Fish spend their entire lives in water, but frogs spend only part of their time in water. Adult frogs breathe with lungs, fish breathe with gills. Also, fish have scales, and frogs do not.
