In order to survive in adverse environmental conditions, amphibians developed behavioral, physiological, morphological and functional adaptations that act together to reduce water loss by evaporation through the skin. Amphibian skin is characterized by the presence of glands scattered throughout the body, producing toxins mostly used in the defense against predators. Over the past 30 years, knowledge about the amphibian skin, especially in toads (Bufonidae), has been expanding through toxinological and morphophysiological studies mainly performed by the group of the Cell Biology Laboratory of the Instituto Butantan. However, many aspects about the morphology (cell biology, histology and ultrastructure) and functioning of the skin glands and about the biochemistry of the cutaneous secretions, related to the adaptations to the terrestrial life of toads, remain poorly studied. This work aims at the study of the defense against predators and desiccation through the analysis of the skin of four species of Bufonidae from the group Rhinella marina inhabiting different biomes, using a comparative and interdisciplinary approach.
