Research suggests that boa constrictors don't suffocate their prey, but cut off blood flow, causing circulatory arrest.

constrictors do suffocate/choke their prey

Research suggests otherwise.

I think perhaps what the boas are trying to do is cut off blood flow, and suffocation comes with it. Either way, their prey is DONE. Hehe

Yes they can sense the prey's heart beat so they constrict them & then consume them

Eureka! I knew this!
