I how can I tell the sex of red-eared slider turtles? And when will they begin to mate?

Question

I have 3 aquatic turtles. I am concerned they will begin to mate and lay eggs. To prevent this, I need to deterine the sex of each. Help!!!

Answer 1

Red eared sliders are particularly easy to sex. The females get much larger, and the males have VERY long front claws, as well as longer tails. You can usually tell for sure when the turtles are around 4 inches long... The females may end up laying eggs anyway, whether they are fertile or not. If you end up with 2 males and 1 female, prepare for some major aggression.

Answer 2

If your turtles are not adults, 4 – 5 years old, you probably can’t sex them but the general rule is that on males the claws are longer, the bottom of the shell is concaved, the tail is fatter and longer, the vent opening on the underside of the tail, called the cloaca, is farther from the body and closer to the tip of the tail.
On females the claws are shorter, the bottom of the shell is flat, the tail is shorter, the cloaca is closer to the body than it is to the tip of the tail and females are bigger than males of the same age.

Answer 3

They will start to mate at about 3 years in captivity.

Male turtles will have long, skinny tails and in-curved bellies.

Females will have wide, short tails and flat or outcurved bellies, and usually be a bit bigger.

It is hard to determine sex of very young turtles.

Answer 4

I know very little about reptiles and such, but I heard that a male turtle (actually, I think it was a land tortoise), that the male belly is concave to fit over the female, and the females is flat...also something about the tail (already mentioned).

Good luck!

Answer 5

by the shape of their tails female short and sqatty--male is longer and real tappered...basically if the look very different from each other then you have one of each... i would get some turtle books to see their breeding conditions... maybe there will be love in the air..lol

Answer 6

If the turtle is mature the underbelly shell of the male will be slighty concave and the female's would be flatter.

Answer 7

EVEN WITH ALL MY ANIMAL WORK I JUST FOUND THIS OUT FROM A FRIEND OF MINE WHO RAISES TURTLES...
THE MALE WILL HAVE A DEFINATE INDENTION UNDER ITS BELLY. THIS IS A FUNCTIONAL DENT THAT HELPS THE MALE PROPERLY MOUNT THE FEMALE WHEN MATING.
