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!

No problem, thought it might be useful to see what their BRB's get up to in the early hours  |

| One thing has puzzled me though and I think Cliff would most likely answer this one being around BRB's for a while, Why do they change colours ? |

This is definitely a question for the biologists.. I understand why they may change colour though..
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 ? |

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.

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.

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  |

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. |
