Stygichthys typhlops (Teleostei: Characiformes), phreatobic fish from eastern Brazil: Comments on Sampaio et al. (2012): A response.

Criticisms of scientific papers are always welcome, as long as they are wellsupported by appropriately contextualized data or information. When dealing with new approaches, the criticism becomes even more pertinent, because it points out directions towards eventual solutions or interpretations of data, many times unviable in cases where the literature is scarce or inexistent. It is precisely from this perspective that science is built: mature and properly supported discussions among different approaches of a same theme.
