How do you tell if a yellow bellied turtle is a boy or girl?

Answer...sort ofIt is almost impossible to sex the creatures whilst they are still infants. Once they have reached adulthood the females tend to be bigger in size so if you have a female and males you should be able to see a clear difference but you will have to wait anything from 8 months to two years for this to happen. Sorry I can't a more detailed answer.

you cam tell the sex of yellow bellies by the size of their tails the male has a longer tail
