This species is dimorphic in size meaning the sexes show different characteristics.{{cite journal | vauthors = Viana PF, Feldberg E, Cioffi MB, de Carvalho VT, Menezes S, Vogt RC, Liehr T, Ezaz T | display-authors = 6 | title = The Amazonian Red Side-Necked Turtle Rhinemys rufipes (Spix, 1824) (Testudines, Chelidae) Has a GSD Sex-Determining Mechanism with an Ancient XY Sex Microchromosome System | journal = Cells | volume = 9 | issue = 9 | page = 2088 | date = September 2020 | pmid = 32932633 | pmc = 7563702 | doi = 10.3390/cells9092088 | doi-access = free }} 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. 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.Viana, P.
