• mammalian
  • Although platypus venom has a broadly similar range of effects and is known to consist of a similar selection of substances to reptilian venom, it appears to have a different function from those poisons produced by non-mammalian species: its effects are not life-threatening but nevertheless powerful enough to cause serious impairment to the victim, which can lead to temporary paralysis.

  • venom
  • Many archaic mammal groups possess similar tarsal spurs, so it is thought that, rather than having developed this characteristic uniquely, the platypus simply inherited its venom from its distant ancestors. (wikipedia.org)
  • Unlike snake venom, there appears to be no necrotising component in the Platypus' venom - although some muscle wastage has been observed in cases of envenomation in humans, it is likely that this is due to the inability to use the limb while the effects of the venom persist. (wikipedia.org)
  • spur
  • In 1991, Keith Payne, a former member of the Australian Army and recipient of the Victoria Cross (Australia's highest award for valour) was struck on the hand by a platypus spur, while trying to rescue the stranded animal. (wikipedia.org)
