Chaerilus under UV light

[Gigas]

Chaerilus is in its own family Chaerilidae so you would have to be a closely related family, there are 22 species of chaerilus so you might want to see if infact every species in the genus does not fluores.

Thank you gigus, I know NOTHING about Chaerilidae, but would love to see one of our members run a good study... It was in fact an excellent observation in the first place.:clap: I think whoever it was who said that possibly the pigment covers it up may be on the right trail.... Interesting to run a post molt scorpion under the light, before the exoskeleton hardens up.

...
hopefully Alex tietz can tell us if the adults of C.rectimanus flouresce

Hi George,

unfortunately I´ve lent my uv flashlight at the moment. I´m going to test it as soon as I get it back which will be soon.

I am conducting an experiment right now with my chaerilus. I have enclosed them in each enclosure. Dave also gave me a module to see how they react to different kinds of lightings. I also conducted my own separate experiment I will keep you updated on what will the results be. BTW Dave I also conducted an experiment with regards to the chemical composition of their exsos.

I'm following this thread because it is very interesting, I'm not at all as intelligent as most of you :worship: and I find all this info very beneficial.

Good point EAD063 :clap:

One note I found on this subject (at this location LINK ) says that "Newly molted scorpions do not fluoresce." It seems to be all inclusive, is this true?

Since it is the 'hyaline layer' that holds the 'fluorescence substance', can you separate it out somehow?

Here is an interesting article about "Chitin in the Hyaline Exocuticle of the Scorpion" and an experiment conducted. ( LINK )

Also as I have read this layer is so durable that even in fossils there is a notable degree of fluorescence.

Keep up the diligent work, thanks Thaedion

Yep, freshly molted scorpions do not fluoresce.

Hello again, I hope this might be of interest to those studying this subject, and anyone else for that matter.

Here is a LINK to a PDF article titled "Extraction, Isolation, Identification and Distribution of Soluble Fluorescent Compounds from the Cuticle of Scorpion (Hadrurus arizonensis)" very interesting and (for me) deep.

The theory that i am looking is.. remember those toys that glow in the dark if the fluoresce is low we just need to put it near any light source except open flame for it to glow more this might sound funny and ridiculous but I am conducting an experiment with this set up I will be keeping you guys updated from time to time.

so what you are suggesting is that if the cuticle is "charged" so to speak, then it may flouresce more, much like those glow-in-the-dark stars etc. an interesting theory. what sort of light were you thinking of exposing it to?

 

[Vixvy]

I am using an ordinary fluorescent light and also the natural sun light but i am not exposing it to much just enough for me to say that its charged already. I am monitoring there fluoresce from time to time.

I knew that but just wasn't thinking... Perhaps the specimen could be examined on a habitual basis, every few hours or so, or try to keep it under a lamp to speed up the secretion process while examining.... I have no clue about the scientific nature of that, but a cricket molted in my tank yesterday and was all white, and hung out at the lamp for a while and already he has all his colors back, seemed odd to me, i would just be scared of frying the scorpion. This is an excellent thread, had all of this information been looked past before?

ive also seen my crix and other inverts that molt where total white, i keep my crix on a dark container and those that molt on my tanks get their color back a lot faster than those inside the container, so i think light helps on the coloration of inverts, and do you wonder why those inverts that live on the deep sea and caves where white? so i think light has something to do with it. :? and i hink there is a big difference between bulbs and sunlight right?

 

[SimplengGarapal]

My C.celebensis has a faint glow. Really very dim compared to other species.

You said that happens with your other inverts too? Maybe a good part of this expirment would be like I said, exposing a juvenile, post molt, to a strong heat lamp and monitoring VERY often, to find out if there is ever a point where it glows stronger than usual, thats a good starting ground to know when the flourecence starts to dissappate.

heres what im thinking about, remember those isometroides (spelling) that are specialized on hunting down funnel webs and only eat funnel webs? maybe there was an organism that specialized on hunting scorps using their "glow" so maybe early Chaerilus tried to adapt so that they can survive, then they tried to get rid of their glow, then as prehistoric times past by those scorpion specialists vanished, but chaerilus still kept their adaptation, then those few scorps that still have their UV glow multiplied and multiplied, then new species emerged, they finaly manage to survive. but still chaerilus kept their adaptation until vixvy discovered it.

 

[Vixvy]

I am currently conducting my experiments with my Chaeriluses I have received a module from Dave. I will be throwing the results as soon as me and Dave have decided on one point. I also conducted a separate experiment for me to have some more results and observations.

My theory was similar but not as in depth. Since they belong to their own family I figure that they had to have split somewhere down the morphological path and eventually the glow evolved out of them... I figured this maybe the first advancement that new world scorpions have made.. Either that or they have some differnt excretory system that "doesn't feel like" producing the flourecent material..... I assume the flourecence served some purpose in the last 300 million years.

Does anyone know the newest, trait that they evolved? I mean..they had to have come frmo a single cell at one point.

Bro, whle you're at it. Let me also point out our observation that C. celebensis has thick consistency venom, like a syrup, that is stringy almost like a spider web. I saw this on three occassions, two of them when I got stung.

wow, was that a new discovery for chaerilus? good observation alakdan, i think im now starting to have interest on chaerilus.

 

[Vixvy]

Thanks for that info alakdan i have seen those before but i will make sure that your observation will be noted.
