Teleost fish are a species-rich vertebrate group that has conquered diverse ecological niches on six of the seven continents. The founders of modern ethology, prominently among them Karl von Frisch, Erich von Holst and Niklas Tinbergen, already noted the behavioral diversity and striking cognitive abilities of teleosts. Indeed, there is lots to study, from the ability of the archerfish to shoot down airborne prey with a water jet to the complex social systems of cichlids from the great East African lakes. More recently, the cyprinid zebrafish (Danio rerio) has risen to the ranks of a premier model system in biomedical research, largely owing to the optical accessibility of its larval stage. Detailed brain atlases that link structure to function are now available, as are high-resolution computational maps of kinematic motifs and an ever-expanding library of transgenic lines and mutants. While these advances have revealed basic principles of vertebrate neural circuit development and function, the mechanistic insights gleaned from zebrafish studies do not transfer easily to the questions asked by researchers interested in teleosts with different lifestyles or more sophisticated behavioral repertoires. This satellite symposium aims to prepare the ground for cross-fertilization between the different communities, bringing together speakers with zebrafish neuroscience background and experts working on the neuroethology of other fish species, including archerfish, bettas, cichlids and sticklebacks.
