Hello all,

A little bit of context (not really necessary but figure probably doesn't hurt):
I've had two Russian tortoises for 10 years. I got them when I was really young and didn't take the best care of them, and only relatively recently have been doing my best to course-correct. I had always assumed they were female because the previous owner told us they were. However, when Katrina mounted my other tortoise (don't worry - they're separated now), I realized that I should double check. I know that mounting doesn't necessarily mean reproduction but can also be a dominance behavior, but I figured it's worth double checking. I took them to a reptile shop and they claimed that they were both male, but I'm not sure how much to trust them because they seemed unsure (first thinking they were both female, then 1.1, then both male) AND used some factually incorrect justifications to make the claim (such as that their plastrons were concave - a trait not found in Russian tortoises). I am pretty confident that the other tortoise is male; he's pretty typical in that regard. Not sure about Katrina though. What do you think?

Relevant information:
She is 7 inches long
She has never laid eggs but has recently been digging more than usual: could be that I recently upgraded her enclosure with a deeper substrate or could be more.
She mounted my other (likely male) tortoise and seemed to ejaculate? But could have been a poorly timed dispensing of urate. It was indiscernible from other urate stains I've seen.

Maybe it's my computer, but your pictures don't show up for me.

Others better than me will weigh in, but sure looks female to me...

Female. 7 inches would be a very large male, and the tail would be huge.

Thanks y'all! I had suspected that she was female but the mixed messages had thrown me off. I'll double check the sex of my other tortoise, trying to disregard what others have said and just thinking about the actual traits involved.

In most species there are observable behavioral cues, but Russians of both sexes are so darn scrappy that they defy the norms.

I may have been overconfident that the other was male. He/she typically holds her tail to the side and has a hook, and is a little smaller at around 6" but still I'd expect the tail to be longer in a male of this size. Also I made the mistake of cohabitating them in a pair for years and she never tried to mate with Katrina despite being of size. I'm thinking she's a smaller female but anyone mind giving me a second opinion on her as well?

If you know she is at least 10 years old, I would say female as well
