What is the mechanism of action for the hemotoxic venom produced by Yarara snakes?
It targets blood cells and tissues, proving highly effective against the circulatory systems of mammals and birds
The venom profile of the Yarara is intrinsically linked to the success of their preferred adult diet. The venom is characterized as hemotoxic. This means its primary physiological effect is the targeting and disruption of blood components and surrounding tissues. This chemical action is highly disruptive to the circulatory systems of warm-blooded animals, such as mammals and birds, leading to internal hemorrhaging or coagulation issues which rapidly subdue the prey. This specialized hemotoxic activity strongly reinforces the evolutionary drive for adult snakes to secure high-value endothermic meals, as the venom is optimized precisely for attacking these systems.
