During the metamorphosis of Xenopus laevis tadpoles, tissue concentrations of corticosterone and aldosterone did not change significantly in forelegs and hindlegs; they increased in tail, liver, skin and intestine. The rise of corticosteroid concentrations appeared in tissues which were deeply transformed during the first part of the climax, when plasma levels of corticosteroids also increased. Highest tissue levels, attained at the mid-climax, were maintained at least until the end of metamorphosis although plasma concentrations of two steroids were then abruptly fallen. Tissues able to retain corticosteroids reacted as Vertebrate "target tissues" and transformations which took place in them could be dependent, at least partially, on corticosteroids.
