Resumo(s)

Like most animals, but unlike humans, the chemosensory systems of fishes are vital for many important behaviors, such as food-search, predator avoidance and reproduction. However, as fishes live in water, the chemicals that they detect often differ from terrestrial animals, and many remain unidentified. In fishes, olfaction and gustation are more anatomically and functionally separate than in mammals, although still overlapping, and fishes also have single chemosensory cells and CO2 and O2 detectors in the gills. Given the diversity of fishes, and their life-histories and habitats, it is difficult to generalize about the role of chemosensory systems in their behavior. Nevertheless, this article will attempt to do so.
