Chromosomal analysis of Centromochlus heckelii (Siluriformes: Auchenipteridae), with a contribution to Centromochlus definition [PDF]
Neotropical Ichthyology, 2020 Historically, there are divergences in the species allocation between Centromochlus and Tatia. This study aimed to generate the first cytogenetic data about Centromochlus and, by analyzing a population of Centromochlus heckelii from the Amazon River ...

Diet and foraging behavior of Ageneiosus inermis (Teleostei, Auchenipteridae) [PDF]
Neotropical Biology and Conservation, 2020 Ageneiosus inermis is the largest species of the family Auchenipteridae (Siluriformes) and has a primarily piscivorous diet, although no comprehensive data are available on the habitat use of this species. Given this, the present study describes the diet
