Answer:
Amphibians lay eggs.
Explanation:
Amphibians include frogs, toads, and salamanders. They are vertebrates, so they have a bony skeleton. Most amphibians live part of their lives underwater and part on land. Amphibians reproduce by laying eggs that do not have a soft skin, not a hard shell. Most females lay eggs in the water and the babies, called larvae or tadpoles, live in the water, using gills to breathe and finding food as fish do. As the tadpoles grow, they develop legs and lungs that allow them to live on land (aka metamorphosis). Even after they change, amphibians still have soft moist skin, and nearly all of them have to live in damp places, so they don't dry out.
