why some corns dont constrict

That's possible. I have yet to see one of mine try to constrict a f/t. Although from what I've read around here, and in my own experience, many don't even feel the need to constrict a live pinky. I have had two or three take them down without constricting a bit. On the other hand, I have had one who took an hour to contrict before she was satisfied enough to eat!

That's for sale???
Some of mine constrict, some don't. My amel always constricts, and he does it for a long time. He's always been on f/t. I'm having a hard time buying the heartbeat theory too, or else no one told my snakes about it. For that matter, my Green tree pythons constrict too, and they always hold on for quite a bit before eating.

I'm talkin' to YOU.
Yeah... if you ever see a corn eat a live pink rear-end first, you get to hear squeaking all the way down. I think it has to do with a) how secure the corn feels vs. the prey, and b) how much 'struggle' the prey puts up.
Most corns feel secure enough eating a pink or fuzzie that constriction is ignored. I've noticed this even when the pink is dangled from tongs infront of a hatchling corn. When the snake starts getting to hoppers, if the hopper is just found lying there, the snake generally won't constrict. If it's dangled... most will strike and constrict. Some will refuse to take it until it's set down and they can examine it. Others will gingerly take the mouse from the tongs.
It takes all kinds.

My own theory is that it doesn't make sense to expend more energy than necessary. Those who waste "energy" have less of it to put toward reproduction, which impacts their genes' success. So, in the wild where competition is heavy, those who use it most efficiently are most likely to pass on their genes and therefore they adapt (both individually through "learning" and over generations through "evolving") toward that standard.
Since they start out with food items that do not need to be constricted, they don't waste the energy on constricting them. If you give them a pinky and they aren't constricting it, and you use tongs to help the pinky put up a significant struggle, (assuming you don't scare the hatchling off the food) they will start going "hey!" and constricting it as necessary. That's what I've observed anyway, is that they will begin to constrict as their prey puts up enough of a struggle. Those individuals who learn that they need to constrict (in order to subdue their prey or keep from being harmed) will do so more often than those who have never seen live or "animated" food.
Obviously they will vary in both directions... some will constrict more than necessary, and some will not try to constrict even when they have dangerous prey struggling with them. But the above "happy medium" seems to be the most obvious tendency in corns, at least as I've observed it.

I think Serp's theory is valid from what I've seen.
When I used to feed live prey exclusively, I had a large male that would suffocate its prey, but usually not by standard, coil constriction. This guy would wait for the mouse to get in position, then he would throw part of his body at the mouse, pinning it to the viv glass, or water bowl. He would actually crush the mouse to death by pushing it against something. It was strange to watch, and I've never seen another corn do this even once.

it refereed to a African rock python, that is underbelly senses pulses. so i was wondering if it applied to corns and most captive bread coloubrids. so thanks every one for you reply. i was just a idea. lol. i luv when discussions go on like this.
