hi i have 2 caglei map turtles, there only small but im wonderin how can i tell there gender coz im hoping for 1 of each so they can breed in the future.

How old are they? It's usually very difficult, if not impossible, to accurately sex turts until they are 3 or 4 years old, however in Maps it can sometimes be done a bit sooner as sexual dimorphism is more obvious.

In all species of turtle the male has a bigger tail than the female to enable mating, it's longer and fatter and the cloaca is nearer the tip. In females the tail is shorter, the cloaca is roughly in line with the back edge of the carapace, and the tail tapers sharply to a point after this.

The difference in tails is more obvious in Maps than in some other species.

The other main difference, but usually not so obvious until they are older, is that males develop longer front claws than females, in some species there's a huge difference which is impossible to miss, in others it's a lot less obvious and may only be noticeable if you have one of either sex to compare them.

One male and one female isn't an ideal ratio for breeding purposes, you may find that the female gets far too much attention from the male, even resulting in injuries, in which case you'd need to separate them.
