Exactly why I haven't talked to him since then lol, thankfully there are other places to talk and learn without all the riddles.

I don`t quite understand what you`re saying about having a large group of females?

Given the infrequency of parthenogenic reproduction and the low numbers of viable eggs actually produced, you would produce a lot more babies with just one or two male-female pairs.

Thanks for answering.

I ment more in the wild than in captivity, if for some reason there was no males in an area but didn't word it very well

This would never be the case, its probably statistically impossible for that to happen.

Not monitors but an all female lizard species that reproduces without males. Pretty cool.
I could have sworn they used to think that they changed sex at will but appears that more research has been done and that females just act like males for better fertility rates. Might be a different whiptail that changes sex. Cool none the less.

Have any of you tried transillumination?

[Gatorhunter1231]

There was a big thing on transillumination a while back on varanus.nl but I believe it was inconclusive (for babies).

Not necessarily, when you consider that varanids island-hopped their way throughout Southeast Asia. If a monitor was one of the first few to arrive, parthenogenesis would be a very valuable tool. Although not monitors, Mourning Geckos have this technique mastered...

Good point, I was thinking of aussie species though, not many chances to island hop haha.

Maybe thats why komodos and salvators developed that skill?

Hi, V. komodoensis is originally an Aussie species.

Are the aussie speciments the ones that show parthenogensis? Ofcourse I don't know if the theory is viable anyways as panoptes have also been observed doing this and they do not island hop as far as I know?

I`m not sure which animals you mean when you ask if the Aussie specimens are parthenogenetic (other than Panoptes)?
We have no idea how common it is in the wild, perhaps fairly regular in a number of species (and also throughout the world), and it doesn`t necessarily need to be simply for the purpose of island hopping.
