This was a mature male Brachypelma sp. ("Honduran Rust Rump") that attempted a postultimate molt. Basically, as you can see from these pictures, this is a deathwish. I do not believe there have been any males successful in doing this (anyone heard of this happening?).



This was his exuvium. Notice how the carapace and legs are fused together, and several legs remain trapped in the exuvium (the legs are the white things sticking out of the top). His abdomen was not regenerated, and remained on his body.



And here he is. Notice he lost both pedipalps, which is common among males who attempt postultimate molts. He also lost both fangs.
Because of this, he obviously would not be able to survive on his own, so I decided to euthanize.
How did I do this.....?

No better way to put it.....Blondi chow.







...And that was the end of Mr Rust Rump and his dysfunctional internal clock.........

Poor little fellow... he looks so pitiful. But he died an honorable death in the fangs of such a magnificently beautiful blondi!!!

I believe somebody on this board has a male which has survived a post ultimate molt. Is it Joy or Immortal_Sin? I believe it is one of them and there is a post about it somewhere I believe with pictures attached.

yes, it's Joy, she has a B albopilosum that survived, I think he's close to 3 years past maturing date too!
His legs are all deformed, but his fangs are fine...hope she sees this thread!

Yep, it's Joy and she's had about three males complete a postulimate molt. All Brachypelma spp. from what I can recall too.

Hello safetypinup,

There had been some reports about survivers on the different mailing lists and the most amazing thing: Jay Stotzky had a Poecilotheria regalis male which had two(!) post ultimate molts! See the mails he posted to the arachnid_world List (15. & 17.04.2000). Photos of this male you'll find in the book of Verdez & Cléton (2001).

all the best,

If by "Giant Spider" you mean tarantulas, it would be from the outside in. :)

Martin,
That's definitely amazing! I assumed it was definitely possible for males to survive one (or even two!) postultimate molts, but had never heard of it first-hand.
As for the other Brachypelma spp., perhaps this is common w/in the genus...? I have heard of other Brachypelma spp doing this, but, until now, had not heard of one surviving for very long.
Martin--Did the male P. regalis come out with pedipalps intact? Was he able to breed after his molt(s)? I'm curious!
