Ontogenesis of oxygen chemoreception in aquatic vertebrates

In aquatic vertebrates, peripheral O(2) chemoreceptors initiate compensatory physiological and behavioural responses to hypoxia, beginning at very early stages of development, to maintain sufficient gas exchange across the skin or gills. This review highlights the morphological and physiological studies, particularly those of zebrafish, that have contributed to the current understanding of the development of O(2) chemoreception and the response …
