This article studies the morphological remodeling of olfactory organs in the fire salamander (Salamandridae, Caudata), from the larval stages of ontogeny to the adult and throughout the course of the annual cycle. The fire salamander exhibits adaptations to the aquatic environment during premetamorphic life and terrestrial adaptations after metamorphosis. During adulthood, the annual activ

Until recently, structural studies on olfactory organs were mainly considered in an evolutionary context. The morphological variability in these organs was interpreted as differences between species or higher taxonomical ranks. A few papers concerning this subject have shown that morphological differences might occur even within the species, depending on the
