The metamorphosis of a tadpole to an adult frog involves a thorough reconstruction of the animal's body. Positive feedback regulation would ensure that the animal completed its transformation.

Positive feedback regulation of prothoracic hormone secretion by ecdysteroids is the mechanism that determines the timing of metamorphosis.

Metamorphosis is the biological process by which an animal develops physically, including birth and hatching, and which involves marked and relatively rapid changes in an animal's body structure due to cell growth and differentiation.

Some insects, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, often with changes in diet and behavior.

In case of frogs, and toads, forelimbs are formed under the gill pouch, and the hind limbs are visible after a few days. This is usually followed by a longer phase in which the tadpoles are fed a vegetarian diet.

Tadpoles use a relatively long spiral intestine to digest this food. Recent studies suggest that tadpoles do not have a balanced homeostatic feedback control system until early stages of metamorphosis.

At this point, their long intestine shortens and they prefer insects.
