Uh i cant remember where i heard/read this but like there was some study done or something where they hooked up pressure sensors to a chicken and fed a large constrictor and the pressure from the squeeze it exerted was like the pressure of multiple buses per square inch. The even more incredible thing was the snake held the same amount of pressure for like 10-15 minutes or something. Which was really surprising to all the scientists. I wanna say they did the test with an anaconda. It was pretty cool stuff.

Let me go try and find a link...
