Corticosterone acts synergistically with thyroid hormones, when it is increased during prometamorphosis (period when hindlimbs emerge).

Terms from Etkin (1968) are also used to describe the general stages of amphibian development: premetamorphosis (early larval stage that precedes hindlimb development), prometamorphosis (period of rapid hindlimb development), and climax (frontlimb emergence [FLE] and other dramatic morphological change).

In an earlier experiment we tested whether tadpoles in early prometamorphosis (Gosner stages 2628) were capable of accelerating metamorphosis in response to an immediate drop in the water level.
