Saturday morning Sheba and/or Nina picture

I've known for a while that Nina changes color slightly during the course of the day, every day. For some reason, I was under the impression that I'd already talked about that, but apparently I haven't, so that's what we're discussing today. (And for once, no whining about the uncleanable terrarium! Everybody wins!)

For most of the day, she looks like this:

There's a light-colored, repeating diamond design down her back, with dark triangles to either side and a main body color that's kind of in-between.

In the mornings, though, she looks like this:

Much darker along the backbone, and in general.

I didn't find any websites that would confirm this for me, but I assume this is most likely a temperature-regulation thing, and she just wakes up dark because that's the best color for absorbing heat from the sun. Not that she actually sees the sun, but you know what I mean. I don't know what time of day she switches from one to the other, never having tried to find out, but on the day I wrote this she'd changed at some point between 9 and 11 AM.

Some species of anole are also able to change from brown to green, but Anolis sagrei (Cuban brown anole), which is Nina's species, doesn't do that: they're always a shade of brown.

I think she changes her body colour according to her mood, and it seems that the colour will be darker if she's stressed out. Well.. at least thats what National Geographic said.

Maybe Nina isn't a 'morning person'.

Fish do a similar thing, I believe.

Darker to blend better with surroundings at night?
