I'm not to sure about sexing but i think if you see bulges at the base of the tail it will be a male if not then its a female.again I'm no expert so you might want to double check.

Timors, much like most Odatria and Euprepiosaurus, can be sexed visually by using various different methods (when all combined together, you can increse your certainty).

What I have found to work in Odatria, Euprepiosaurus, Varanus, and Soterosaurus, is using the contour/shape of the dentary bone to determine the sex. Males will have thicker dentary bones, as well as a distinct, noticeable curve to it, whereas females tend to have a less-curved, or linear contour to their dentary bone.


Another method which often works, is the width of the heads. Males typically have wider, broader heads, whereas females are more narrow and tapered.


Male monitors also have noticeably larger nasal cavities than females, perhaps due to the need for a greater amount of oxygen intake-given their greater activity levels than females. Due to the larger nasal cavities, the external opening to the nasal cavity(the nares) will be often be substantially larger/more prominent in males than females, creating a more amplified/exaggerated 'ridge' in relation to the slope of the top of the cranium.


While sometimes these differences may be subtle, and difficult for the untrained eye to see, when each of these characters are combined, you are often able to come away with an accurate idea of the sex of your animal. While the photos I used are of members of the Varanus prasinus complex, the same techniques can be applied to many other species belonging to the subgenera I listed, including V. timorensis.

Good luck!

Yes I could not have explained it any better Bob. These are the factors that I determine the sex with too. So far it as always turned out to be accurate for me although sometimes you get one in the mix which resembles both in a way.

What a great reply to the post,good on yah Bob.

[James566clugston]

thanks alot for the help this helps loads what do you guys think of the sex

[arborgoanna]

That looks like a male to me. Beautiful V. auffenbergi you've got there![/i]

[arborgoanna]

Here's a look at the curvature to the dentary bone in your individual, very typical of males.

[JStroud]

Have to agree great post Bob, thanks for replying!
