thanks! i feel like an idiot !

Yep..when the prey exhales they tighten up making it harder for it to inhale

rub it in

exhale, tighten is pretty much the rule with constricting, thats how it works pretty much and why the prey dies so quickly.

With all constrictors when the prey exhales, they tighten. This prevents the preys body from expanding to take in another breath and they suffocate.
