I have a 4 y/o Argentine Boa, that I thought was a female. I have been trying to find a mate for "her", and I thought it would be a good idea to probe "her", before I bought a male. "She" is about 6 feet and 8 pounds. I just got done probing "her", and probed 10 scales on each side! There was no pressure on the probe, it just slid right in. This leads me to believe that "she" is a he. This is the only Argentine I've owned, so can anyone tell me if there is anything different about Occidentalis to make me think anything other than it is a male? Thanks for any advice.

I had it in my head that BCO probed a little deeper than other South American Boas, so I had to check. But they are no different. "Reproductive Husbandry of Boas and Pythons" by Richard Ross and Gerald Marzec on page 46, Table I, gives an average depth of 10-11 for males and 3 for females. Hope this helps.
Good Luck-

Thanks for the response. I was afraid of that. When I originally bought "him", it was with a yearling Dumeril's Boa. The owner told me they were both females. At the time I wasn't planning on breeding Argentines, so I wasn't concerned about the sex. When I sold the Dumeril's, I probed her and she was a female. As the Argentine got older, I decided to look for a mate. I have been reading enough posts lately about mis-sexed snakes, I thought it would be a good idea to probe "her" before I made a deal for a male. Good thing!! I guess now I will be looking for a her to go with him. But I am going to probe "it" once more before I finalize any deals!!!!!! Thanks again.
