These are my two girls. As you can see the they are both different in color. I was wondering if they are the same locality or are they different?

This is my first lady...I think she is pretty

This is both together..sorry about the dull picture

The on with the yellow legs looks like my female.
She was told to be a "New mexico" Crotaphytus collaris.

For the pale one, I don't know.

The pale one looks JUST like Dexter. Do you know what kind this is? It really looks like Dexter with just the little bit of yellow on his feet, etc. When he sleeps at night, sometimes his head gets a brownish color... that always facinates me why it does that...

Why colared head gets darker when its cold ?
This question is for me !

Its a physical answer.
You know that white clothes attract less sun than black ones.

When a collared lizard is basking since an hour or more, its head become paler.
Its a sign that he needs to absorb less heat by changing color.
When it gets cold, his head turn to black because it wants to get the most efficient heat absorption from UVA rays.

So... Collareds have a metabolism that dynamicaly changes pigmentation like chameleons but not for a camouflage purpose, for a variable heat absorption system.

I think thats why there are localities.
Lizards from the south like Mexico ones are whiter than north ones like bicintores.
"Desert" collareds are closer to equator and have open sources of light since years.
"Forest" collareds are far away from equator, have longer winters and have many natural sun blocks.

Does it sounds right ?

Sounds right to me, but I'm no expert.

Anyways, I was looking at a website on green iguana anatomy and it says they have a parietal eye "third eye" on top of its head, and some lizards have them.

I looked at my lizards and sure enough they have this little grey transparent looking tiny like-scale on top of their heads.

If its a parietal eye it should detect light changes, probably for thermal regulation and detecting a predator like a hawk overhead.

Does any one else see what I'm seeing on top of the lizard's heads? I think it is just 1 mm big.

Your blueish female is very nice. I used to have a breeding stock of lizards that looked just like that...males and females. They had come from a locale in Texas. I got my original breeding group from a man in Chicago, Illinois.

the other female in your pictures definately looks like a female specimen from New Mexico. I have a buddy in NM that sent me my very first collared lizards. At the time they were referred to as the subspecies baileyi. They were from the S. central area of New Mexico.

Hope that helps.

PS...The man in Chicage named his blue lizard "Bluestars."

thanks alot for the reply...

I was confused about how different they looked. I found them wrestling today. At first I thought they were fighting but they were not. It was the funniest thing!!
