It contains components meant to immobilize and disable the prey, as well as digestive enzymes, which break down tissue to prepare for later ingestion. [36] [40] The venom is very stable, and retains its toxicity for many years in storage. [36] Snake venom, in general, has a complex and ongoing evolutionary process, and rattlesnake venom is no ...
It also contains specialized digestive enzymes that disrupt blood flow and prevent blood clotting. Severe internal bleeding causes the death of the small animals that this snake eats. After envenomation, the rattlesnake is able to withdraw from the dangers of sharp-toothed prey animals until they are subdued and even partially digested by the ...
The corn snake is named for the species' regular presence near grain stores, where it preys on mice and rats that eat harvested corn ().

The Guiana rattlesnake, previously recognized as C. d. dryinus, [3] is now considered a synonym for C. d. durissus.In fact, after the previous nominate subspecies for the C. d. durissus complex became the current nominate for Crotalus simus, which now represents its Mexican and Central American members, C. d. dryinus became the new nominate for the South American rattlesnakes as represented by ...
Two main hemotoxic effects are caused by rattlesnake venom. First, zinc-containing metalloproteases act upon capillary endothelial cells to inhibit platelet aggregation and hemorrhage. [ 14 ] Second, the platelet antagonist crotalin creates a severe bleeding effect as it binds to the surface proteins, blocking aggregation.
Crotalus oreganus, commonly known as the Western rattlesnake or northern Pacific rattlesnake, [4] [5] is a venomous pit viper species found in western North America from the Baja California Peninsula to the southern interior of British Columbia.
