What type of venom primarily targets and destroys red blood cells in *Crotalus oreganus*?
Answer
Hemotoxic venom
The venom composition of *Crotalus oreganus* is predominantly classified as hemotoxic. This classification indicates that the toxic components within the venom are specifically structured to attack and degrade red blood cells and the walls of blood vessels. This action leads to severe localized tissue damage at the bite site. While this mechanism is highly lethal to the snake's usual prey, which consists of small mammals, it represents the primary mechanism of danger posed to larger animals, including humans, following a bite.
