    Hello,

    I had this Rads for more than 5 years now. The tortoise is close to 6 years old and weights about 3,975 g and about 10 inches SCL. I know it is difficult to visually sex Rads but wonder if we can give it a try. Hope the following photos provide some hints. Can it be certain a female or male one way or the other?

    Thanks,
    Sean

    I can only guess. Looks male too me. I can't see the length of tail to be sure if they look as long as I'm thinking they are.
    Is there any concaving on the bottom shell? The first one looks like it has some.

    The only way I could tell the difference between male and female radiata was to lay them side by side. It's obvious when you can see both male and female side by side, but not so obvious when they're alone. The male does have a pretty fat tail, though.

    Yours is looking female to me.

    I took some additional photos to help with the guessing. Mainly to show the tail. I do think in about 3 or 4 years I will know for sure or if he flashes before that. I also included a photo with another endoscopy female on the right to compare. This big Radiated disguises very well and got me really puzzled.

    Interested in @zovick thoughts but the plastron, tail and anal scutes look female to me.

    Yes, I agree. The tortoise appears to be a female at this time going by all the signs Dan mentioned.

    Based on the flared (open) supracaudal scute it is leaning to look more like a female. Males tend to have more of an inword spoon like formation of this scute. I am almost certain it is a female, time will tell.

    I am in the neighboring state of Utah, do you know anyone here that has them? Are yours producing yet? I plan on applying soon, so hopefully I will be in the market within the upcoming months.
