veileds veil a resonater

[chamitch]

hello i noticed a buzz comming from my veield. i felt it as well as heard this. my cham always likes to hang out on me and walk around. anyway how coem i never read anythign about that in liturature?

thanks

[J-Man]

I don't know but it's happened to mine before. Mine was constant though... it was like a burp or it was clearing its throat.

[chamitch]

no not so much a burp. but a buzzz. fibrating.

[Trace]

Normal. Completely normal. The males do it for some reason... mating? announcing their presence? I must say, when one of my males starts chirping, the rest of the boys perk right up. It's hilarious.

Cheers!

cool thanks. i never read about that before. thats cool probably for mating or communicating liek the dinosours. mayeb veilds are smarter than we thought.

[Collide]

yes mine does that too its really funny makes me laugh god chams do all kinds a weird stuff lol

[meow_mix450]

lol wow sounds likef uun:p Does Male Panthers do this???

[Trace]

Does Male Panthers do this???

Sometimes, but I've found not as much as my Veiled's.

well i guess what i have to do now is figure hwo they use there veil as a resonator. and why. perahps a trip to yemen is in order.

All the veileds, male and female, do this. My old female buzzes almost every time she comes out. From what I've read, its supposed to be some form of subsonic communication. The vibrations would be transmitted very effectively through a branch I'm sure. They seem to use it for a variety of things including excitement, alarm, possibly defense.

The Rhampholeons I use to have did this all the time as well.

[chamitch]

but it makes u think there veil is specifially designed to do this.

[Trace]

The Rhampholeons I use to have did this all the time as well.

Oh yes! I forgot about those guys. Mine chirp like mad when you pick them up.

I don't think the casque (veil) has anything to do with the vibrations really. As some of the members have stated, there are many species that make these sub-sonic noises and they don't have to ornamentation the Veiled's have. I think the Veil evolved to make them appear bigger to predators. Also the Veileds come from a fairly dry part of the world, and the casque is shaped so that any water that falls on it, it naturally flows into their mouths.

I could be way off base on that theory too...

Cheers!

hmm perhaps. but also is remarakable drum like with a hard bone on the outside. that would amplify the sound as well as catch water. i just recall learning of dinosours that have things that resemble teh veil that use it for communiction. chameleons dotn gt teh credit tehy deserve i think. does anyoen have a evolution site of chameleons?

[choriona]

hey....you gotta remember that anything "known" about dinosaurs is just an educated guess. Even professionals argue about how thir evidence says "this is the way it was" and some other professional will say "nope, my data suggests that this is the only way it could have been." They are both right because they can never be proven wrong. Actual behaviours do not get preserved like bones do. :)
And yes, I've also read that the casque is designed for collection of condensation. The dew beads on it, then travels down it towards the mouth. The thin structure of the veil could also be a means of cooling the blood stream to bring the core temperature of the animal down when it gets too hot. It's like our extremities, they get really flush when we are hot because the blood is close to the skin surface trying to lose heat.

[J-Man]

I miss my cham :(

[Wuntu Menny]

Right on the money, Choriona. Trace as well. There are several schools of thought on the function of the casque. An additional theory proposes that the increased surface area helps warm the animal faster after a cool night.

As far as the amplifier theories, let's not forget that chams are effectively deaf therefore the generation of any audible sound is virtually pointless.

I read that these vibrations are defined as 'infrasound' vibrations/communication. There were also some studies that showed the chameleons could pick up on these vibrations for mating reasons, territorial defence and predatory defence. They theorize this is some means of communication, but nothing more than a threat to rivals and courtship ritual to females and what I mention below about Brookesia. Anyone who has bred veileds, including myself, will know that while they are mating, their veils go out of control with vibrating actions, especially (my) female's.

The Brookesia do this only (according to what I read) as a defence from predators. When they are picked up in the mouth of a passing predator, the vibrations give a sensation through the mouth of the predator that they have never felt before, and they are momentarily stunned/confused, dropping the chameleon and letting it escape into the leaf litter. Of course this doesn't always work, but it is a selective trait inherited by those that escaped death by doing this many moons ago and lived to tell about it.

so u guys say its for cooling? does the veil contain alot of blood vessels that suggest this?


peace

[choriona]

same deal as elephantes - the huge thin ears are for cooling the body through cooling the blood temperature.
I would suspect that the veil is full of capillary beds.
As for the vibrations, my male does that when I grab him quickly, but I can feel it in his body too. That would be an interesting defence mechanism. Brock, you should pm me your sources, I'd like to read that.

[Brock]

It's been 1.5 years since I read that information, and I could not for the life of me remember the sites I read them at. Most of it came from discussions on KS and people gave links from there. You can always try a Google search. Sorry.
