INFORMATION ABOUT BIOTOPE:
Description of the area surrounding the biotope: The Rio Negro is the second largest river in South America with many river tributaries that ultimately end up with smaller forest streams. One of these forest streams is Igarapé do Daracua located near Barcelos.
Daracua village is located in an inaccessible place deep in the Amazon rainforest, and it’s easiest to get there by boat.
Description of the underwater landscape of the biotope: This black water habitat strewn with dead leaves characteristic of the middle of the Rio Negro and is home to a diverse group of fish species.
The dense leaf litter covering the bottom provides both food and shelter for many species
Description of the parameters of the habitat: especially during the low water season, is hot (28-30C), extremely acidic (as low as 3.5 pH in this particular habitat) and with almost no mineral content. It is rich in tannic and humic acids, both of which contribute to the dark brown coloration.
