Males will have much larger tails than females.Hi all,
As title, can you help me to determine the gender of the two radiated tortoise ?
Both of them are about 12~13 inches, thanks.View attachment 340557View attachment 340558
Thanks for reply.Males will have much larger tails than females.
The plastron of a male ( the belly of the shell) will be rather concave.
The plastron of a female will be rather flat.
Top one looks probable female, but I cannot see the tail very well. Bottom one is harder to tell, but could be a male. Is the plastron at all concave on the either one?Hi all,

Both #1 and #2 could be females, but it is still hard to be positive.Thanks for reply.
I have three radiated, all of them are about 13 inches, the tail of the other one is very long and plastron is concave. I know it's a male.
But the other two, make me confused.

They are about fifteen years old, I got them from my friend only few months.How old are they? How long have you had them?
Thanks for response.Both #1 and #2 could be females, but it is still hard to be positive.
Normally, I can sex my own Radiated Tortoises by 7 to 10 years of age and about 10" or so in length. Those two should be old enough and large enough now to tell the sexes, but with Radiated Tortoises, there is always a slight chance for error until they either lay eggs or show their penises.Thanks for response.
In your experience, what kind of size and how old are them could be determine gender accurately ?
They are about 13 inches PL, 15 inches SCL and 15 years old now.
Just FYI, those are my photos of a pair of Burmese Stars in you post #6. They are not Radiated Tortoises, in case you did not realize that.Here’s a photo I picked up. The one on the right is female. Left is male
Because I got the two Radiated tortoise only few months, I still not put them together with the known male one.Normally, I can sex my own Radiated Tortoises by 7 to 10 years of age and about 10" or so in length.

Have you tried running warm water over the plastron to see if either one will evert a penis? This takes a lot of time and patience, but it works. Sometimes you have to do it on a number of different days to get any result.
If you have a known male, has he tried to breed with these two possible females? Are they at all cooperative?
Finally, I think both of them are females.Normally, I can sex my own Radiated Tortoises by 7 to 10 years of age and about 10" or so in length.

In the photo of #1, that female is lifting herself up (cooperating) for the male. You may actually have had a successful breeding there. Good luck!Finally, I think both of them are females.
Thanks for your advise.
Ok, I will keep observing #2.In the photo of #1, that female is lifting herself up (cooperating) for the male. You may actually have had a successful breeding there. Good luck!
I can't see enough of the rear of the tortoises to tell anything about the #2 animal.
Yes, do not incubate the eggs at temperatures over 31.5C (88-89F). Safest would be to stay at or below 31C.Ok, I will keep observing #2.
By the way, could you give me some advice about how to avoid scutation asymmetries of new born tortoise ? Thanks.
Thanks for your kindly help, Bill.
Finally, both of them laid egg, I house them together at late April.
#1 laid two eggs on 16 June, #2 laid six eggs this morning.
