Despite the fact that parthenogenesis occurs without the need for sperm cells, fertilization is a prerequisite for a mother to become gravid in the first place. 'Fertilization' in this case doesn't carry the literal meaning of being fertilized by sperm. Mature females of parthenogenic species (of reptiles and invertebrates) are triggered into entering a fecund stage via excretion of certain chemicals inside the body.

Something worth peeping - linko. Pages 73 & 74 illustrates the embryonic development process in parthenogenic scorpions.

In your case, Lester. The development of the embryos had probably taken place at different stages. Some earlier than the rest, and those later consumed most of the nutrients and developed into full fledged scorpions. While the others remained in embryonic form and failed to develop as the elder siblings sap most of the nutrients meant for the entire brood. Like the sibling rivalry in honey bee colonies. But then again, 'probably' is a vague word and carries no bearing in the scientific world. This topic is a free for all really.

Something else worth reading - linko.

If the above applies, could there be a plausible possibility that Virgin Mary (mother of Jesus) was a parthenogenic Homo sapiens?

You have pm.

very interesting article.. Reproduction in scorpions, with special reference to parthenogenesis .. need sometime to digest .. will be back shortly ...

btw , i decided to proceed with the article on the Word of the Day: Parthenogenesis which is shorter lol ... . also an interesting article...
some point to quote for discussion sake ........

For explaining everyday life—babies, puppies, puberty—the mommy-daddy story of procreation works fine. But at life's edges, conventional biology, like conventional physics, breaks down. As you approach the speed of light, time slows and distances shrink. And as you approach extinction, genes find new ways to pass themselves on. Scientists call it "reproductive plasticity." A Komodo dragon manufactures a mate. A shark's got to do what a shark's got to do.

from the above quoted ....if it is true, does this means those parthenogenesis sp say our some of our scorpion sp are slowly moving towards extinction stage ?? or was it at a time near extinction stage before our time???? if either of the two is true... what can we do to help on this like our thread says: Scorpion Conservation in this prematured hobby of our locally........

would like to hear some views from you guys...... on this

We're not there yet, but we're on the way. Two years ago, British officials authorized human procreation using sperm, nuclear DNA from one woman, and mitochondrial DNA from a second woman. Three weeks ago, they proposed legislation that would approve the creation, for research, of "a human embryo that has been altered by the introduction of any sequence of nuclear or mitochondrial DNA of an animal." The categories we've taken for granted—mommy, daddy, people, animals—are blurring. We're losing our innocence.

wow just imagine that ........ !!!!!!! human reproducing of one self without the need of a mating from a male .... hmmm i don't like that

Scorpion conservation your interested? I am here to collect them not conserve them.

If you want to conserve just stop buying scorpion.

If your refering to conservation of the scorpion hobby and your really pure genuine like 99.9% gold. For instance, stop harming the hobby by selling dangerous sp and potentially hazardous sp to our enviroment and start show some real knowledge about them.

Hmmm ....... nah ............not as pure as gold which i wish ......... just another reflection of what u are tortoise laughing the lizard ????

btw define real knowledge.. as mentioned by you ...since u said about real knowledge... let see ur real knowledge explained or is it just keeping quiet like the other few previous posts when asked .. no wonder so many people said so much abt you in msn chat ... lol can't stop laughing while i am typing this .. hahaha if u would in the chat too .. hahaha
anw .....



Scorpion conservation your interested? I am here to collect them not conserve them.
yes .. i am interested in conversation . if u are not then you go ur path i go mine and i prefer it that way if u were to understand my "english" i no "police" so can't catch u if u do not want to conserve any ... lol ...

stop harming the hobby by selling dangerous sp and potentially hazardous sp to our enviroment
guys ... all of u all .... chef say we are selling and harming .......... so shall we quit the hobby or what?? ... i see quite a few thread sell hots too ... and the replier itself ... " selling to anyone that seems genuine " ... ( self understood )

btw ... with request from others , many told me to leave you alone ... well ... this will be my last post to you .... enjoy ur day ...

p/s : if it is of any personal .. do drop me a pm .. i will reply via that ..


Anw aside from the above mentioned, chuk aside the issue and the person, i need to apologize here , with regards to conversation of scorpion . i rem.. sometime back a discussion was brought up ... wildcaught vs captive bred . havesting from the wild for selling WC sp and captive breed sp to provide for the hobby itself .... but sort of halt ...

many of us i believe go for CB sp as not to disturb the wild population .... some only allow WC sp for starting of new culture of sp. and 2nd generation onwards will be Captive bred before sold to provide for the hobby. do correct me if i am wrong ...

personally i think this a good way of conversation too......


p/s: deathpion congrats once again for the new molt

Books of science and NatGeo tell me that parthenogenesis has been happening since God Almighty invented the first living things. Procreation back then in unicellular living creatures was only possible via parthenogenesis.

If you are an avid follower of Darwin and his beautifully carved theories (which I am not) you may want to read up on the following a little more -

1. Superfecundity - the ability of a species to create more offsprings than is necessary to replace themselves (this is the predominant case in most parthenogenic living organisms).

2. Finite pool of resources - i.e. food, space, shelter, mate etc etc. This inherently limits the number of survivability of offsprings. Not all offsprings enjoy maturing up into adults.

3. Variation in genetic constituents between individuals within the same species.

4. These variations are also heritable - i.e. read up the Punnet square under the Mendelian genetics. The people in the leopard gecko and snake thread love this one to bits.

The above is not something I came up with by myself. It came from spending time with books and strolling about on the sandy beaches of googletopia and be less full of oneself.

It's a very vague parallel to synonymise parthenogenesis with the extinction of a species when it is obvious that this is a variation (or just another form of evolution rather) in the attempt to keep on procreating, instead of light-out.

God knows better.

LOL, Whatever la, humour yourself, is spinning to a dead end anyway with no improvement like anything you potray here. Sorry didn't read your pm by the way, nothing personal and nothing worth discussing with you.

I voice out when i feel my hobby is being endangered by certain individual but no point keep looking at you spending your time defend your reputation. I ain't interested in that.

End of my discussion on this part.

damaged my left finger. nearly cut the finger off. article on ld50 will be on hold for awhile since i can only type with 1 hand. will try my best to finish it asap.

Thank you. Love all your fat scorpions pics.

WTH happen with ur finger sam?

one of my female Parabuthus transvaalicus scorpion molted from 6th instar to 7th instar.. finally matured and able to breed this sp..

kind of strange this time round for this molting. Normally from what i observed, all my current Parabuthus Transvaalicus scopion molt in flipped position meaning the back facing the sub, but this lady molted in not the usual flipped position but the opposite way ..... and the time took for final molting is much longer than usual too ...... took more than 15hrs so far and still molting..... is this usual ????...

anyone encounter this before? ..

is she still breathing?

This post has been edited by mangolicious: Apr 21 2010, 04:08 PM

yes still breathing .. and able to move once awhile like while in molting.... til now more than 17 hrs aready . and still molting ...........

omg. finger crossed and good luck with you.

Any improvement or it just stuck in the same position?
Lets just wait and see but i dun think it will make it if its stuck in the same position for so long

thanks my finger crossed too

much improvemnt i must say.. most of it is out of the old exo ... left the stinger bud part .... do u think i shall exercise some aids on it ?
it is the first time it took so long for a molt to complete....... or is it because it is the last molting that why it is so long ?

A lot people will against this but im not here to debate but anw, if it were me, i would have pull it out already.....
It should be easy to pull it out without any problem unless it is already dried up and it get stuck real hard inside...
But dun blame me if bad thing happen thou...

All my lychas scutilus have molted into 2i. Waiting them to molt into 3i now.
Unfortunately some of them had become victims of cannibalism >.<

Aaaawwww, that sucks
How many left?
Buthidae never do well in communal especially before they reach adulthood
I have some Balsasensis babies that was cannibalize by their tankmate before too

I would suggest separating wuts left now.

Ryo around 20 smthg left.
Rideon, yeah I've separated them into smaller container.

I wonder is lychas scutilus really a rare scorpion?
