Are sex ratios in A. andersoni 50/50?

[Jennewt]

I have a group of 5 A. andersoni, and they turned out to be 1:4. In talking to two other keepers, they seem to have a surplus of females too. Is this just coincidence, or are there more females than males out there?

Initially it would seem that more females are produced than males. I think it's a little premature to draw any conclusions.

I would ask anyone who has andersoni to please post your sex ratio. If a dozen or so people respond, we will at least have some anecdotal evidence.

Yes, There are two pet shops here that is selling young adults, for 30 dollars each an they are all females!!! An the store owener got them for 15 !!!! It's the same as the boscaii, I've had 5 females for the last 4 years they layed every year an still have yet to get a male!!! I guess you have to be in a click!!!

I'm really surprised to have so few replies to this post. I'm sure there are people who obtained A. andersoni juveniles (unsexed) and now know their sexes.

The ones I just raised turned out about 50/50, of around 40 - 50 animals.

Of my five it appears I have one male and four females. Three of them are younger so it is hard to tell, but I would say they're ladies!

Here's another report of a mostly-female group:

John S's experience is reassuring. I admit that the reports are anecdotal, but I have yet to hear from anyone who has gotten a mostly-male group of andersoni.

Could sex ratios be affected by temp,ph etc? having one person with a 50:50 ratio of males and females is not indicative of a general trend. Please note that this post was started with a question, i dont know the answer.

 

[Molch]

could it be a temperature -or environmental influence during development that warps sex ratios, like in crocodiles? Maybe in captivity they are raised at generally higher temps than in the wild?

Hi, thought I would add my 2 cents as I've been interested in finding more andersoni. I purchased one in 2009 and it is female.
