The goal of this work is to present a collection of drawings and figures depictingthe species present in our country.To achieve this, our main sources of information have been the works of Ringueletet al. (1967), Reis et al. (2003), and López et al. (2003; 2006), as well as the onlinedatabases of W. N. Eschmeyer and Fish Base.Each species has an individual factsheet with selected images, including some fromanatomical research works. All the works referenced are mentioned in each factsheet.This is an open-ended publication. As such, it will require permanent updating,which will depend on the good will and collaboration of the ichthyological community.As compilers, we understand that this contribution not only provides valuableinformation, but also highlights the work of men and women who are part of the richhistory of our national and regional ichthyology.
