Below are two images of a Virile Crayfish taken from a culture pond. Right cheliped has two pairs of propodus and dactylus with second set emerging from larger typically positioned propodus.

Very interesting. Are both pairs functional? It looks like the larger set may be..

Did you originally catch the cray from the neighborhood pond?

Nope, well yes and no, a bird picked it up at the pond then dropped it, and I cleaned it before putting it back.

Quite a tale. Good Job. Hardly an IQ below 130 on this forum.

Oh and if you want to know how bad of shape it was in here what was wrong, it was missing 3 legs, and was preg, and was dropped on the road.

Not referring to your IQ, merely referring to your audience, can't get too much past these guys. Sorry about your autism, that sucks, if you let it, but for some it is a gift. Really does not matter much to me. Rule number one: Don't talk about fight club, Duh that's not it. Here we go. Don't collect and keep at home any fish or aquatic critter and release it. You can introduce pathogens into your waters that our native fish have little to no resistance to.

I reckon I will trust your bird story.Makes sense, otherwise you would have simply said " I mistakenly released a crayfish before I realized that it could be detrimental to the environment"

Not for me, it caused a lot of probs when I was in public school, I lost a lot of friends, and such, but it mainly helps with stuff, although it doesn't help with my hypoglicymia(not spelled right).

Its not a atural pond, actually its not even a pond, its a pond for rain run off, and they stock different fish so they get more people buying houses because you can fish there.

Larger pair functional. I do not think it is genetically based, rather something went wrong early in the regeneration process.

Hopefully it doesn't cause any probs, that would go for BIG $$$$ at a lfs or a aquarium club, or even a public aquarium.

Now that's polydactyly! Even if it's regeneration, it's still going to involve genes. If it is similar to what happens in vertebrates, it like results from sonic hedgehog (SHH) expression. Thanks for uploading and sharing!

Was all this in the vicinity of Par Pond on the Savannah River Nuclear site? Seems they have enough two headed turtles and other odd things pop up there, if you can believe the "Rural Legends" around Aiken County, SC....

But seriously - anyone know if this is at all common? It seems that either genetics or injury to an animal that sheds its exoskeleton would result in things like this occasionally; I wonder if it would actually drop off in the next molt.

The limb has been regenerated through at least 4 molts to get to current size so not like to be lost by simply molting. If limb amputated I bet regrowth would be normal.
