Phylogeography of the reticulated python (Malayopython reticulatus ssp.): Conservation implications for the worlds' most traded snake species. Published by The Company of Biologists Ltd. These effects may be important to recognize and treat properly in rare cases when constrictors injure humans.
We propose the latter 'red-out effect' as another possible mechanism of prey death from constriction. These and other constrictors can exert pressures dramatically higher than their prey's blood pressure, suggesting that constriction can stop circulatory function and perhaps kill prey rapidly by over-pressurizing the brain and disrupting neural function. In both species, peak constriction pressure increased significantly with snake diameter. We studied the scaling of constriction performance in two species of giant pythons ( Python reticulatus and Python molurus bivittatus) and propose a new mechanism of prey death by constriction.

Despite its importance, little is known about constriction performance or its full effects on prey. Constrictors immobilize and kill prey by using body loops to exert pressure on their prey. Snakes are important predators that have radiated throughout many ecosystems, and constriction was important in their radiation.
