Oceanic islands and seamounts play an important role on the origin and maintenance of biodiversity, however, these environments are still poorly understood. Here we report 15 new records of reef fish species for the Davis Seamount, Trindade Island and Martin Vaz Archipelago, in the Vitoria-Trindade Chain (VTC). Such isolated sites are among the last frontier for shallow reef exploration in the South Atlantic, and more scientific effort is needed to better understand their biogeography and to help in conservation efforts.
