The neotropical region exhibits the greatest worldwide biodiversity, with species diversification history being related to the puzzling geomorphologic and climatic history of this region. About 6000 fish species inhabit the Neotropics, representing one of the richest ichthyofaunas in the world, both in terms of the number and taxonomic diversity of species. The order Osteoglossiformes (bonytongues) represents one of three ancient teleost lineages and is a unique model for integrating data from cytogenetic, genomic, and biogeographical studies, as it has at least one representative on each of the southern hemisphere continents, except Antarctica. Among them, only the charismatic arapaimas and arowanas occur in the Neotropics, with their phylogenetically closest relatives inhabiting freshwater areas in Africa, Asia, and Australia. In this chapter, we provide an overview of integrative approaches that have brought advances in our understanding of their biogeography, demographic history, genetic diversity, and chromosomal differentiation evolution. Then, we discuss how ongoing and future studies will expand our knowledge about neotropical bonytongues, with potential implications for their conservation.
