Hi,
I've been looking at Southwest Speckled Rattlesnakes and it seems that they aren't as toxic as other subspecies, is there any truth to this? From what I understood, the species as a whole could be potentially lethal. Every LD-50 chart I read says the dose is much higher for this subspecies than any other subspecies, and the same methods of injection are used. Any clarification would be much appreciated.
Thanks,
Evan

Evan:
There is not much bite info on this somewhat secretive snake. Like any venomous snake is best not to find out just how toxic they are by personal experience. Yes, they seem to be less toxic than common species out west (atrox,scuts,tigris)but what does this really mean? Not a whole lot by my estimation. The bottom line is avoid finding out in a personal way because they all have a potiental of lethality.
Too many people rely on LD50 charts, they just show the relative toxicity between species and have nothing to do with humans. Remember mice may be more suceptable to their venom since they are potiental prey whereas we are not on the menu. These are lab experiment cafefully constructed to eliminate variables. When a snake bites naturally there are all sort of variables, add a human into that equation the variable go through the roof. My B. asper is 22(sc) in one chart and C. m. pyrrus is 9.6(im) on another. I would much rather take a bite from the pyrrus than the asper anyday if I had to get chomped by one or the other.
