How do you tell the difference between male and female Red Eared Slider Turtles?

I have two baby sliders. I have read about the male is smaller and the claws and tail is longer. But with the two I have it is difficult, anyone have any answers for me? Also, someone told me you can tell the sex of them by the patterns on their bellies; is this true?

How do you tell the difference between male and female Red Eared Slider Turtles?
the bottom shell of a male has a large dent in it while the bottom shell of a female is relatively flat.
Reply:I'm not sure if you can tell the sex by the belly patterns, but the male will have a rounded indentation on his belly shell. Males also have longer claws, and their vents (on the tail) are further from their body.
Reply:Babies are tough to sex. In most cases, we need them to get a little older first but the issues are:





MALES have longer, thinner tails, longer fore nails and in-curved bellies





FEMALES have short, wide tails, short front nails and flat or outcurved belly shells.
Reply:Peek under the shell! lol
Reply:There are fairly distinct differences between the male and female red eared slider, but they may not be obvious until the turtle reaches sexual maturity. For males, this is about they time they reach 4 inches in length (about 2-5 years old). Females are sexually mature when they reach 6-7 inches in length (may take 5-7 years).


A. Male red eared sliders have much longer claws on their front feet than females. As well, the tail of males is longer and thicker. The cloaca is located farther from the body in males, and males also may have a slightly concave (curved inward) plastron.
Reply:To tell the sex of a turtle look at the underside shell. Males are concave, it is bent inwards slightly so they can mate without sliding off the females back, and the female's is flat or slightly pushed out.
