How does a boa costrictor snake kill its prey?

The snake bites the prey and wraps around it. Contrary to what you may have heard, they don't crush bones, but rather seem to exert enough pressure to kill the prey by preventing it from breathing.

There is a new hypothesis that they generate enough pressure to stop the prey's heart, but while the evidence is suggestive, no definitive test has been made.
