Pyon don't actually crush their victims, but asphyxiate them. The snake will only stop constricting once its victim stops exhaling. The slightest breathing cues the snake to squeeze even tighter.
Once the prey is in its mouth, the green tree python pushes its meal down with the help of rhythmic movements. It will swallow its prey while still alive; sometimes the muffled screams of their victims can still be heard from inside the snake's body.
