Description

edit
 
In Brazil

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.[9]
