In the early stages of development, amphibians live in the water they breathe with gills as an adult an amphibian lives on land and uses lungs to breathe.
All amphibians go through an metamorphosis.

the word "amphibian" comes from two Greek words: amphiwhich means both and bios which means life. This refers to the fact that all amphibians are hatched from eggs in water and live in water until metamorphosis occurs and they can live on land.
Larvae are the hatched form of an amphibian that is different from the adult. A larva of an amphibian may be free swimming (e.g. tadpoles) before the metamorphosis to an adult (e.g. a frog).

Most amphibians undergo metamorphosis during development. The axolotl is an amphibian that does not undergo true metamorphosis, remaining in a semi-juvenile state.
During amphibian metamorphosis liver enzymes, hemoglobin, and eye pigments mature. In frogs and tadpoles, physical changes include losing the tail, horny teeth, and external gills. The hind legs and forelegs develop.
They grow lungs, and lose their gills.
The platypus does not experience metamorphosis. It is not an amphibian. When first born, the platypus is about the size of a bean and barely resembles its parent. However, like all young of mammals, it gradually develops the features of its parent as it grows. This is not metamorphosis - it is growth.
A frog is classified as an amphibian. They are known for their ability to live both on land and in the water, have moist skin, and typically undergo a metamorphosis from tadpole to adult.
Metamorphosis is not a form of reproduction. It is a biological process that happens after birth.
