Must see macro pics of the molted Siamese twins!

[Rindy]

Rob, Darling what are you guys doing down in that basement?!!:?
or
please take the tarantula cage off the microwave.....

 

[violentblossom]

I'm rooting them. :worship:

That thinking is off base.

If I remember the biology behind it correctly-

When (siblings or other related) oragisms mate the instance of traits that are "hidden" will show up.

Sooo ONLY if the parents had genes for this "trait" that them being related would have an impact of this showing up.

IMO - this is an developmental anomoly ( two spiders fuzed )
twins ? possibly

JUST my 2 cents...
but hey I'm just a chemist.

This may very well be a developmental anomaly. However, inbreeding CAN lead to developmental abnormalities as well, showing up in increased frequency the further down a generation is inbred. This has been shown to be true with D. melanogaster, X. laevis (both popular models for study) as well as with plants and birds, among others. Inbreeding may not be a factor in this case, but that line of thinking is not entirely off-base.

It should also be noted that with animals that produce a large number of offspring (i.e. Tarantulas), the possibility exists of a random oddity being produced. The probability of that happening with two genetically distinct individuals, however, drops, but the possibility is still there. Separating the eggs from a sac to ensure a high survival rate provides evidence of this being true. If these oddities were allowed to develop in the sac, they may have been eaten by the other sac-mates.

Good luck with those two, er, three Rob, and keep us updated!

I hope to see more changes in these T's. It's unlikely that they will survive awhile, but wonders never cease and science has a weird way of making things "happen" I wish the best , and I'll be following this!!!

 

[drgonzo]

Is this from the same T that had the sack with the high mortality rate ?:? :?

Thanks for the info

My response was more knee jerk.
People tend to think that Brother-Sister; Father-Daughter offspring will automatically yield deformed/mentally challenged children.
That is how I read the posters intent, if that was not their intent then I apologize.

This is amazing! Talk about an oddity, that little bugger with the backwards legs would fit right in at a Ripley's Believe it or Not Museum. If it survives I'd bet anything you could tong feed it with no problems. How would it drink though?
(It also reminds of the the deleted scene in the Exorcist where Regan does the backwards crab-walk down the staircase )

I remember that part...creepy!!

 

[robc]

Whoa......

These kids remind me of that 3-eyed fish on The Simpsons. Maybe you should name this guy "Blinky?"

Are there alot of really BIG power lines around your house?!?
Keep posting the fantastic weirdness....we're learning alot more than we did in Science class!

LOL....I will

I agree....this probaly happens a lot more but they are eaten before the sac is pulled...I pulled this sac at 21 days.

There is no way they were in breed....the male wasn't mine LOL

 

[Vidaro]

awesome! i really want to see pics of them while they are molting, im really curious on how they did that(both cases)

Also have you thought about how u r going to feed them? coz it wont be lng before they need to feed, if they survive that is...(dont wanna jinx you)

 

[scar is my t]

That is REALLY weird to have a backwards t and Siamese t's. Good luck with them. Hope they dont die to quickly. I would love to see them in 3 years....

Probably have to hand feed, but then again, animals are capable of amazing adaptations. I think the inverted invert will be even more problematic, but instinct trumps these anomalies sometimes. The exposed booklungs are a little disconcerting- wonder if dessication would be more of a problem. Either way, you've got a good start on an invert Mutter museum. Good luck, Rob.

No prob!

But you are right, sometimes people tend to think that inbreeding can have immediate deleterious effects, when in actuality that is not completely true. For the most part, it takes more than one generation of inbreeding before abnormal phenotypes manifest themselves.

I'm a chemist too, so i'm right there with ya!

 

[MorganD]

Wow, Rob, amazing...both from one sac eh? You should contact National Geographic haha..

 

[Totty]

Haha, Amazing!

 

[OxDionysus]

If they mature you should try to mate the twins with the backward legged! lol

 

[robc]

Here is a video of the Siamese twin....the pics are in the video that are already posted but I wanted my youtube viewers to also see it. The black egg in the vid was removed LOL

Most interesting thing I come across today.
Thank you for sharing Robc
