Reptile & Amphibian Forums

Hi~ It's my first time posting here in the forum. I keep one fully-grown and one juvenile mali uromasyx. I think my big uro is male based on his(or her??) coloration and I'm not sure about sex of the little one. Both have pores of similar size.

Anyway, here's a problem with them. Big uro started biting little one's tail tip when he sees the tail close to his mouth. Does this mean both of them are male ?? Other than tail-biting problem, big guy doesn't seem to be aggressive toward the little guy and they seem to get along well.

Also, Is there a good way to distinguish their sex??

thanks in advance~

You may be on your way to a problem. Watch them closely. Bites are normally made on the sides also.

If I were you I'd separate them right away. Uros have wickd bites and your little one may lose a tail tip, a toe, or a life if the big one gets serious.

The little one looks awfully small to determine sex - a breeder or someone very experienced might, but it'll be harder for you or me. The bigger one will be easier.

This is Turtle - a (so far) female-mimic male Mali. Sex was confirmed by Doug Dix. If you're looking to sex your uro - the marked area is where to look. Turn your uro away from you and lift the tail up over the back. Males will be as above, with two parallel bulges (hemipenes) with a dip in between. Females will either have no dip, or the bulges (tendons) will make more of a V shape instead of being parallel.

Thanks for the replies

I checked the big one for the bulges and found none.

I guess the big one's probably a female ^^

It may still be too young to tell - the bulges develop when the hemipenes do, so check in six months or so. Do you know how old it is?

Unfortunately no.. I bought the big one when it was already big

Small one is probably a yearling.

I'll check for the bulges in six month or so and I'll post again

I forgot to mention that the big one's 30cm in total length

and small one's 20cm. ^^
