Answer

Certain crotalid species have unique toxins. Crotalocytin, found in the Timber rattlesnake (Crotalus horridus), causes platelet aggregation. [8] Mojave toxin, found in some populations of the Mojave rattlesnake (Crotalus scutulatus), inhibits the presynaptic release of acetylcholine, leading to weakness and paralysis. [9] Pit viper venom may also include bradykinin-related peptides that can lead to angioedema and hypotension. [10]
