This chapter examines the biogeography of marine incursions in South America. It summarizes evidence for marine incursions into the continental interior during the Miocene period and considers the effects of these paleogeographic events on the diversification of Neotropical fishes. It identifies some of the main biological factors that may have allowed for the successful invasion of Neotropical freshwaters, including origins from euryhaline or estuarine ancestors with high tolerance for salinity fluctuations.

Keywords: biogeography; marine incursions; South America; Miocene period; Neotropical fishes; salinity fluctuations; euryhaline ancestors; estuarine ancestors
