Wow Brett, that native male has turned out really well. His colours are so vibrant.
Is that one that you bought from Michael Cermak?
The bottom pic is not native though is it?
Thanks Brett. They're stunning specimens! I notice that they both have the black vertebral pinstripe or 'shadow stripe' as I prefer to call it. Were they from the same clutch?Bottom one is NOT native , I just got lazy with the file names and called them all the same thing...
The natives are from Michael , very happy with them too , as usual the female is hiding her head so no good shots of her but I will get her one day...
Yes, they're great examples of an intriguing phenomena. I reckon that the 'shadow stripe' serves to neutralize the juvenile 'ghost stripe' for camouflage purposes. What do you think Michael?Yet another one with the black line we talked about with Dan. Strange stuff.
females mate, females, that's what it is.
That's interesting, thanks for the feedback. I shift my juvies from 2 litre containers to bigger ones when needed but I never had such experience. One solution - don't give here any place to hide. LOL

Hi Dan. Thanks very much for your thoughts on this. I suppose that the purplish-brown juvenile markings serve a similar function. Thanks for the link to that paper, which looks like a good read. 8)Hey Pat,
Your right about the stripe aiding camouflage. However, this is a general trait found in many species (e.g., viridis, C. caninus, B. gabonica) and is independent of stripe colour. It's called disruptive colouration. The idea being that because these snakes coil up during the day when visual predators are around, the pattern along the vertebrae breaks up their outline against the forest, making them harder to detect than a solid (unpatterned) green lump.
A great test of it can be found here; "Visual Predators Select for Crypticity and Polymorphism in Virtual Pre" by Alan B. Bond and Alan Kamil
In the specimens that I bred that have the dark vertebral stripe, I perceived it to be shadowy rather than jet black.Pat, why "shadow stripe" if it's jet black?
... In all the juveniles I reared up, only a handful had this "black dotting" (that's my terminology, just to be different)
Another one this morning. What really threw me, she had no pre-lay slough. The last time she sloughed was on 25th March.
I wonder if she pushed the one egg to the side because she is not big enough to cover them all. There is even a slight gap at the top where she has got her head.
Any thoughts on that?
This happened with one of my clutches Michael. The excluded egg turned out to be the only one that was infertile, despite looking as good as the others. I reckon that the mother can smell infertile eggs and deliberately doesn't include them, as they will soon rot and potentially spoil the good eggs.
Well done michael, have you ever had a female not have a pre lay shed before.
