    I read somewhere that, if you have lizard eggs, you can control the sexes of the babies. I'd heard about this with turtles, but never with lizards. Here is what I remember, vaguely:

    mid 70s-low 80s= female

    mid 80s+=male

    Is this true? I'm not sure where I read this, but I do remember it being a trustworthy source.

    TSD.

    Temperature-dependent Sex Determination.

    That's what it's called. Just thought y'all should know :)

    You can predetermine the sex of Leopard Geckos by the temperature at which you incubate them too. It's not as low as you've stated there for Leos...

    I've heard about this in other lizards (and in a lot of snakes)...

    While I've not seen undeniable proof that the same is true with Anoles.. I did notice that the ones we incubated ourselves did produce a LOT more females than we see running around outside (given a random number of anoles)... out of 20 or so we hatched last year, we only had 4 males... and all the rest were female. Yet, the wild populations around here show otherwise. Going out in the back yard here shows a LOT more males than females. So it's possible the temps inside the house here were better for producing females.
