It is found in Brazil, Colombia, and possibly Peru.

[7] This species is dimorphic in size meaning the sexes show different characteristics.

[8] One study found that the largest female out of a group of 24 was 256 mm in carapace length.

Out of that same group, the largest male was only 199 mm in carapace length.

[8] A study focused on determining how these turtles acquire their sex discovered that it is not environmentally determined rather, it is a genetic sex determination.
