The red side-necked turtle (Rhinemys rufipes), red turtle, red-footed sideneck turtle,[1] William's toadhead turtle, or red-footed Amazon side-necked turtle[2] is a monotypic species of turtle in the family Chelidae. It is found in Brazil, Colombia, and possibly Peru.[2]
Description
.jpg){kind=link}
This species is dimorphic in size meaning the sexes show different characteristics.[3] 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.[3] 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.[4]
