>>1400543Some are far worse than others even amongst the same species. Take the timbers for example- the "canebrake" variety down south are considered to be more lethal than their northeastern kin because their venom takes on a more neurotoxic quality in addition to the standard hemotoxin. Even with that though I'd still risk a wet nip from a southern timber over an eastern diamond back or Mojave due to the sheer venom volume of the former and potency of the latter. The really nasty shit lives south of the border though. A rattler may ruin the next few days for you if you survive it, but a bothrops will potentially ruin your life.
