In insects molting is regulated by ecdysone. In amphibians it's regulated by hormones from the thyroid gland, as is our growth, up to a certain degree. This also illustrates the fact toads are far more closely related to us (both vertebrates) and insects are an outgroup. ^^
The hormone responsible for metamorphosis in frogs and toads is thyroxine. Thyroxine is produced by the thyroid gland and plays a crucial role in regulating the transformation of tadpoles into adult frogs or toads during metamorphosis.

Metamorphosis. The back legs grow, then the front legs. The tail then disappears and you have a froglett.
Frogs and butterflies undergo complete metamorphosis, where they change drastically in form and structure as they transition from larvae to adults. Frogs go through a process called metamorphosis, while butterflies undergo metamorphosis from egg to caterpillar (larvae), pupa, and finally adult.
Dramatic change in an animals body is referred to as metamorphosis. Usually related to frogs and butterflies. Metamorphosis is the process bt which an animal changes into an adult form.
Frogs are said to have " two lives" because of their metamorphosis
It is Metamorphosis.
Frogs undergo a process called metamorphosis, which involves several stages. They start as eggs laid in water, hatch into tadpoles, and then undergo significant physical changes. During metamorphosis, tadpoles develop legs, absorb their tails, and transform their gills into lungs, eventually becoming adult frogs capable of living on land. This transformation allows them to adapt to different habitats and lifestyles throughout their life cycle.
Frogs undergo a process called metamorphosis, which transforms them from tadpoles into adult frogs (tetrapods). This process involves several physical changes, including the absorption of the tail, the development of legs, and the transition from gills to lungs for breathing air. Additionally, their diet changes from herbivorous (feeding on algae) to carnivorous, as they develop the ability to catch and eat insects. Metamorphosis is crucial for their adaptation to life both in water and on land.
