Pterinochilus murinus Color Forms?

[JC]

Thing is if you got a pair of RCF forms right from the wild, and breed it in captivity where the chemicals and insects are quite different the offspring are still gonna be RCF, cause just look most if not all murinis in captivity are the same orange/red. And I am sure no one feeds the the roaches or crickets plants found in the murinis area.

Yes, of course. But the experimental group must be something other than the RCF. We already know what the RCF looks like in captivity.

Agreed! One of the tests for sure would have to be a tan form bred to a RCF, and see is they would come out in form right between the two or would it lean to one or the other.

Normal or typical color form aka NCF (TCF): http://www.birdspiders.com/gallery/p.php?id=178

Dark color form aka DCF: http://www.birdspiders.com/gallery/p.php?id=211

Kalahari color form aka KCF (I just made this up): http://www.birdspiders.com/gallery/p.php?id=282

Usambara Mountains variant aka UMV: http://www.birdspiders.com/gallery/p.php?id=288

Red color form (or orange, take your pick) aka RCF: http://www.birdspiders.com/gallery/p.php?id=308

the first and third spiders r awesum!

Hey Zoltan, do you by chance know if cross breeding is possible between color forms and what the outcome would generate? Typically anyways, if you have experience in doing this.

Thank you. That's helpful.

Don't thinks so. You never know what are the chemicals that may only be found through specific conditions in that region of Africa. May not be as simple as a peat moss/dirt/etc. difference.

It may also be in specific concentrations of the chemicals perhaps only acquired through the feeders exposure to specific plant materials. It is most likely something in the feeders of the regions(if the reason for color forms is actually due to them being from different regions).

But of course I'm just speculating. I was reminded of the idea because I remembered of the relationship between poison dart frogs and the borrowing the toxins from their natural pray and losing their toxicity in captivity when their diet was changed.

i think it would be moreso adaptations due to environment than something to do with the prey they consume - otherwise we would be seeing some wild stuff in captivity

From an evolutionary standpoint, there was natural variation in the population. As the population spread out the color morphs that stood out the most against the substrate color were selected against. Those that blended in were able to survive and oass on their genes in these subpopulatuons.

Its possible, but don't. You wouldnt create a cool color, it'd probably just be the color of either of the parents, or a muddied orange. Nobody would want the slings, and we need to keep species and their color forms separate in the hobby.

coloration in arachnids i think is a debatable and an v interesting concept - particularly given their blindness and how it wouldn’t be related to mate attraction

and i think in some instances it’s to blend in with the natural surroundings and i think in others, the bright coloration serves the same function as in other venomous animals which is the coloration indicates danger and venom - it would be interesting if we could test venom variations within the OBT color forms to test this
