xray sex determination

hi all,

was wondering if someone could give me advice on sexing monitors, in particular emerald tree monitors. does xraying work on this species, and if so, what size would they need to be before this can be done accuratly.

thanks in advance,
t.

I could be wrong, but I thought xraying worked best with larger species.
I would think that emeralds would be almost ideal candidates for saline injection

hi harald,

thanks for the reply! if you could tell me more about sexing using saline inj. or any other methods i would be very greatful.

I read an article sometime ago that Marke Bayless wrote about this subject. I t was pointed to the dumerils monitor and the nile monitor. It said x-ray sexing was very ineffective, and actually seeing them defecate was one of the only true ways of determining the sex. I sexed my 3 dumerils I had with the defecation method.
