new Infensa pair

The previous images dual posted and corrupted themselves somehow. New potentially breeding pair of Hadronyche Infensa. These have more potent venom than a female Atrax Robustus

      Do you know why these aren’t ever mentioned in the ‘most venomous’ lists? I would be interested in reading studies on their venom toxicity. It seems like Hadronyche has the potential to be more toxic than Phoneutria species.
    • RezonantVoid
      @NYAN personally I think they are, it seems like way more people survive Phoneutria bites than these without antivenom. A decent envenomation from H.Formidabillis can cause death in 15 minutes. I know that Infensa venom is currently being farmed and developed as a cure for melanoma cancer which is pretty cool

      Just curious, is this guy in premolt?
    • RezonantVoid
      @WildSpider im not sure it's almost impossible to tell with funnelwebs they give literally no warning signs and will pretty much eat hours before molting, I'm hoping she will molt ASAP so the male doesn't die. It's just become Funnelweb season here so I'm sure he has only just molted and he's probably got about 4 months in captivity

      Pretty sure females of these are as potent if not more so than male A. robustus. @RezonantVoid In terms of the rate of serious envenomations the more potent funnel webs (A. robustus, H. infensa/formidabilis/cerberea/versuta) are significantly higher than Phoneutria sp. Only 0.5-1% of Phoneutria bites result in severe envenomations, roughly 17% of bites in A. robustus lead to severe envenomations and for H. infensa and formidabilis it’s over 50%

      @Dennis Nedry does not surprise me at all. I've always just assumed male Robustus would be more dangerous as the Atraxotoxin is 6x more concentrated in the venom of males than females. But it seems you are right they are more dangerous all around. Formidabilis bites are pretty rare though as they are normally 30m up sclerophyll trees and don't get flooded out when it rains. In a few weeks I'm going to a botanical garden that has them and H.Valida (still medically significant according to Dr Raven, but not as high a rate of envenomation) and I'm 100% intending to catch one

      Bit of an update these guys could be H.Maquariensis I think it is, the males pedipalps look a bit different from Infensa and have cups instead of wrenches
