SafekipediaConstriction is a way some snakes catch and kill their food. These snakes wrap their bodies around their prey, like small animals or even other snakes, to hold them tight. This method helps the snake keep the prey from escaping while it eats.
Most snakes that use constriction do not have venom, but some that do still use this method. When a snake coils around something, it can squeeze very tightly. Scientists have found that this squeezing stops blood from flowing to important parts of the prey's body, like the heart and brain. This makes the prey lose consciousness quickly and stop its heart.
Researchers used to think the snake was stopping the prey’s breathing, but now they know it’s more about stopping blood flow. Different snakes may use slightly different ways to constrict, but the result is the same: the prey can no longer live, and the snake can safely eat it. Some snakes, like boas and pythons, are well known for this method, but others, including some venomous snakes, also use constriction to catch their food.
