The idea of suffocating in the grip of a boa constrictor ’s coils is enough to make anyone heave for breath with trouble . However , some slap-up - eyed research worker thought that suffocation might not be the true cause of destruction from a boa constrictor . Instead , it was bump that feather boa constrictor do just that : constrict their prey to dying .
Death by asphyxiation seems logical . The constrictor wraps around the chest and neck of quarry , restricting their breathing apparatus . However , Dr Scott Boback , a researcher fromDickinson College , notice that the animate being were killed too rapidly for their causal agent of death to be suffocation , so he determine to do some detective work .
The team decided to set up an experimentation to bump out incisively what was going on inside an anesthetized scum bag that was catch in the clutches of a boa constrictor . As described in theJournal of Experimental Biology , the rodent was fitted with rake insistence catheter and ECG electrodes so that the inquiry team could supervise its vitals .
The team may have already predicted the true cause of expiry , but they could never have predicted how effective it was .
Boback sum to IFLScience that there were two primary surprise in their results , " One was the speed at which these thing occurred . " The boa constrictor was express to constrict its target to death before suffocation conduct place .
" Within 30 mo of the serpent protrude to compress , the rat ’s arterial pressure level was plump , " Boback annotate . Interestingly , as shortly as the constriction force per unit area from the snake increase , the pressure in the rat ’s arteries decreased with regard to one another .
" The other thing that we were really surprised with : there ’s multiple bad events that are occurring for the rotter ; it ’s not just the arterial pressure that go down , we also valuate other thing like potassium . "
Everyone needs potassium in their bodies to modulate how fluids and mineral flow in and out of electric cell . It ’s ordinarily regulated in a besotted window . However , Boback and his squad were startled to see that the rat ’s K levels increased dramatically as it was constricted .

Boback mused that this scheme made sense when you see how fast the prey ’s vitals drop . As before long as stock flow stops , the brain fails very shortly after and the animate being passes out . " Actually the very very first thing that plausibly happens is that the rat go out , and this makes inviolable evolutionary sense . If the snake causes the rat to pass out really speedily , then there ’s no danger from that animate being retaliating against you , " Boback explained . An animal that has passed out is much leisurely to keep down and use up than one that is struggling .
In the future , Boback and his team are interested in studying the impression in other sorts of prey . Rats and mammals are known asendothermsor " ardent - blooded " animals . Boback wonders if the effects of constriction and blood flow are dissimilar forectothermsor " moth-eaten - blooded " animals such as lizards . " It would be really interesting to study the results of tightness on ectothermic prey . "
