Starting with insects:
Grasshoppers (hemimetabolism)
Dragonfly (hemimetabolism)
Butterflies (holometabolism)
Amphibians:
Frogs/Toads
Aquatic:
Fish(Such as salmon)
Most metamorphis is not really visible or noticed by people.
These include the hemimetabolism metamorphis of insects. During
this process the Grasshopper or Dragonfly larva will break out of
its old "skin". They usually just increase in size, but during
Grasshopper metamorphis the Grasshopper may get wings.
Fish usually undergo metamorphis when they have to change from
freshwater to salt.
