River stingrays or freshwater stingrays like the Branco River Stingray are in the family Potamotrygonidae, in the order Myliobatiformes. And we’re about to introduce you to another black-colored species in this group. Drumroll, please…
Say hello to the Itaituba river stingray (Potamotrygon albimaculata), also known as the Tapajós river stingray. We talked about their discovery in 2014 along with the Pearl Ray. Found only in the mid and upper Rio Tapajós basin in South America, specifically Brazil, they have a black-brown dorsal disc color with whitish spots everywhere. #Finfact: they have rows of thorns spread on their dorsal side and tail. They have small, numerous teeth to eat whatever it is they eat – and we don’t know what that is.
Their total length is 383-790 mm, and females have 1-4 embryos. And… well, that’s it amigxs! That’s all we know about them so far. The IUCN has not assessed these animals.
