Detailed explanation-1: -Metamorphosis in amphibians is the transformation of the larva to a miniature adult replicate, and usually from an aquatic to a terrestrial or semi-terrestrial lifestyle. Metamorphosis marks the beginning of the end of larval life.

Detailed explanation-2: -In amphibians, metamorphosis is generally associated with the changes that prepare an aquatic organism for a primarily terrestrial existence. In urodeles (salamanders), these changes include the resorption of the tail fin, the destruction of the external gills, and a change in skin structure.

Detailed explanation-3: -Metamorphosis is a biological process by which an animal physically develops including birth transformation or hatching, involving a conspicuous and relatively abrupt change in the animal’s body structure through cell growth and differentiation.

Detailed explanation-4: -Metamorphosis is a process by which animals undergo extreme, rapid physical changes some time after birth. The result of metamorphosis may be change to the organism’s entire body plan, such as a change in the animal’s number of legs, its means of eating, or its means of breathing.

Detailed explanation-5: -Metamorphosis in amphibians is regulated by thyroxin concentration in the blood, which stimulates metamorphosis, and prolactin, which counteracts its effect. Specific events are dependent on threshold values for different tissues.
