 ```How much pressure does an an anaconda, boa constrictor, or python exert upon its prey when it constricts around it? Or what is it an equivelant to in terms of force and pressure per square in perhaps, or overall?```
 ```According to a Science Now article, a 5.5-meter python can create a force of about 1 kilogram per square centimeter on its victim--about six times as rigorous as a firm handshake. Scientists have figured out how to monitor the pressure a boa constrictor exerts while squeezing a rabbit to death. ?Engineers at Carnegie Mellon University in Pittsburgh, Pennsylvania, constructed a "constrict-o-meter" at the request of local zookeepers who wanted a visual measure of the snake's coil power for an episode of BBC's Animal Planet. The device, a pressure-sensitive, quarter-sized plate mounted on the end of a 30-centimeter-long probe, is placed between the snake and its prey, says mechanical engineer Adnan Akay, who designed the rig with two assistants. Wires carry the information from the probe to a laptop computer, which plots the pressure. A 5.5-meter python, for example, can create a force of about 1 kilogram per square centimeter on its victim--about six times as rigorous as a firm handshake.? Source: Science Now: Boa Constrict-o-Meter http://bric.postech.ac.kr/science/97now/02_4now/020405d.html An 18-foot-long snake applies about 12 pounds per square inch (psi) while a 5-footer generates about 6 psi. "... opposed to the common belief that a boa constrictor squeezes its prey and crushes it... it really suffocates it." "... They found that an 18-foot-long snake applies about 12 pounds per square inch (psi) while a 5-footer generates about 6 psi. Jefferson City, Missouri Post-Tribune, March 6, 2002 from Vicky Elwood http://ebeltz.net/column/2002colu.html From How Stuff Works: ?A few snakes squeeze the life out their prey in another way -- constriction. Once a snake has the animal firmly in the grip of its jaws, it loops its body in coils around the prey. When the animal exhales, letting the air out of its body cavity, the snake contracts its powerful system of muscles to tighten the coils, squeezing the body so that the animal cannot breathe in again. According to a Carnegie Mellon University study in 2002, depending on its size, a constrictor can apply 6 to 12 pounds of pressure per square inch. Although this pressure suffocates the prey by compressing the lungs, it can also have the same effect on the heart, speeding up death significantly.? How Stuff Works http://science.howstuffworks.com/snake4.htm ?Adnan Akay, a professor at Carnegie Mellon University, recently invented the "Constrict-o-Meter". The device measures the amount of pressure exerted on a prey animal during constriction. Akay found that an 18 foot Burmese python constricted prey with 12 pounds per square inch of pressure. Measure the number of square inches of surface area of the prey and multiply by twelve to get the total pressure exerted. Essentially it ends up being hundreds of pounds of pressure being exerted from all sides.?

 ```just to make it short when a python constricts a victum it dose it with such forch that its blood rushes to its head rendering him unconshus after a few minutes and the blood vains in the eyes burst befor death it is commonly seen in people who have been constricted to the point ware they passout and a python can put any ware from 6-12 psi on a victum but most snakes you will ever see with be able to put and avrage of about 10 psi on a victum.```
