[DA_GRIZ]

[hornet]

I have heard they can be probed but I have not tried it myself yet.

This questio comes up every now and then and it is always answered the same. But, according to Glen Shea, a PHd in Blue Tongues, in a presentation he made to a Mac Herps meeting there is no sure fire way to sex them other than putting two together and getting babies. All these methods you speak of are 80% accurate or better but no better than that.

Glen mentioned in his talk that some people try to invert the hemipenes but to do this you really need to get the musles in the males relaxed. then, if you pop them, that is great, you DO have a male. But not popping them may simply mean that you have a male and didn't manage to pop them. probing can also give incoirrect results for similar reasons - you may think you a have a female but there is merely strong muscles at work down there stopping your probe.


John Weigal also replied to one of the threads saying they he also coudn't do it. Do a search of "sexing blue tongues" and you might find it. In that same reply he said that keepers in the states are currently using a method whereby they look for semenal deposits in the faeces. So GOOD LUCK!!

The problem of course, is that most people want to be able to sex them for the purpose of either buying or selling a sexed pair. Forget it!!! If they haven't bred then they are an unsexed pair and thats it.

Going off head size is easier with very old animals, ie, wild ones that are probably over 10 years or so. I would have to say, I have never been able to see hemipenal bulges in a bluetongue either. I have a three year old that really puzzles me. One day, I threw in my Shingles with it whilst I was cleaning their enclosure, the bluey went straight at the male shingle, so I thought "Oh, it must be a male" I got the male shingle out straight away, but then the bluey went at both the female shingles, then I thought "Oh, it's may not be a male, it's just a ##### of a bluey!"
