Captive care of southern pacific rattles

Southern pacific rattlesnake Crotalus oreganus helleri hypodermix

Family: Viperidae Genus: Crotalus Species: C. helleri Sub species: C. oreganus helleri

Ive been studying these guys locally for a long time, I have a few comments about them

Venom:

Ok these guys are nasty in the sense they they hybridize. For a specimen that I aquired in the mountain ranges has a venom that was less than expected. when striking a live mouse, typically 4-6 seconds before seizures are apparent

on the beach side of the state I have noticed quite the opposite, mice envenomated from this species typically convulse within 2-3 seconds mind you the snakes are on a hot load and feed bi-monthly Both specimens were roughly same size and weight when this test was given. at the same altitude and same temperatures/humidity.

I have seen some info here and there about these guys carying mojave toxins, and this was come as no supprise to me as we do have some C. scutulatus up north, the specimens I have collected beach side are greenish in tint have have more aggresive nostril scales. These are the ones that drop mice in a matter of 2-3 seconds
