Biotope presentation
The acidification of water comes from the decomposition of plants. This phenomenon changes the color of the water, which tends to turn brown. In some areas particularly rich in organic matter, the water is so dark that it is called "black water".
The Cururu Ray is most often found at a depth between 0m and 5m. However, it is not impossible to find this species at other depths.
