Everyone Was Wrong About How Boa Constrictors Kill

Turns out that heart failure, not suffocation, is the cause of death for constrictor’s prey

We’ve always assumed that animals squeezed to death by a boa constrictor died from suffocation, but a new study has found that they actually die from heart failure.

The scientists at Dickson College “examined the cardiovascular function of anesthetized rats before, during and after being constricted by boas to examine the effect of constriction on the prey's circulatory function.”

After constriction, the rats’ blood chemistry showed system-wide circulatory problems and evidence that the heart had undergone significant electrical dysfunction.
