Just following up from Ash's thread the other day about colour changing, I thought I'd check Jade's colour morphing abilities, and lo and behold, it's true! I woke up at 1am to have a little look see and caught her exploring, so turned on the light quickly and took a picture. Here's the Night and Day comparisons for you to see!

Cool. I heard about it from Dave over at http://rainbows-r-us-reptiles.com/homepage.htm on a different forum. Thought I'd share it here. |

The bowl method does indeed work well...I use it myself frequently for anything larger than a baby. |

I've read elsewhere that a popular and effective way to take pics is to put them on something (ie. floor, table) and put a bowl over top of them for a few minutes. When you take the bowl off they're calm for a few minutes, enough to snap a pic.
I'm planning on trying this "bowl method" myself in a couple days. |

Now I'm really kicking myself for not grabbing a shot or two of my Argentine last night while it was ultra pale so I could show that E. c. alvarezi do that also, but he's still just a pup and is too mellow to hang-on when I have him out, so trying to capture an image while he's on me is really quite a balancing act and tends to put either the camera or the boa at risk.
I'll try again next time he changes, and I'll try to capture my Guyanan doing it also so I can share with the class  |

Looked in my Rainbow Boa book and low and behold:
"Individual Rainbow boas have day-to-night color changes. They are darkest (or brightest) during the day, but take on a silvery sheen, especially on the sides, at night. The ability to change colors in this manner is termed metachrosis."
Did a quick google search for metachrosis and came up empty as far as the reasoning (majority of what I found was referencing Chameleons), but as Cliff said I suspect it's a part of thermoregulation.

Lol Cliff you need to go on a proper diet  .
agree with that, pizza and whisky is much more healthy.
Blahh don't get me started on Whisky I LOVE JACK DANIELS !!!!!! |

What Oscar said is true. I also, however, suspect the extra color during the day helps soak up warmth during that time, much as a black cloth will soak up more heat than white one.

No problem, thought it might be useful to see what their BRB's get up to in the early hours 
I dunno, but this morning all my beer and pizza were gone.... ;-) |

Physics lesson time! Laws of Emissivity state that a black body gives off the most amount of radiation possible. White however gives off less radiation, therefore being white would give off less heat during the night, so the Boas would be warmer while no heat source was available.
I love learning thermodynamics.. NAAAAT.
So therfore making it easier for them to hunt at night without them being hunted for prey right ? |
