concisely after a man killed a rattler in his backyard , the rattlesnake ’s severed head routine and injected malice into the man , in earnest spite him , accord to news reports .
The zombie - like incident materialize when Jennifer Sutcliffe and her husband were work out in their backyard near Corpus Christi , Texas , over Memorial Day weekend , harmonize to KIII , an ABC - affiliate station . Sutcliffe said she tell apart the 4 - foot - long ( 1.2 meters ) snake while weeding , and that her married man decollate it with a shovel to defend her .
The decapitated head of the rattlesnake
But when he bent down to dispose of the snake , its beheaded head bit his bridge player . How is this potential ? [ Image Gallery : Snake River of the worldly concern ]
The answer has to do with the serpent ’s physiology . Snakes are insensate - full-blood creatures , mean they get heat from external reference , such as sunlight and warm surfaces . ( The scientific terminus for this is " poikilotherm . " )
Because snakes do n’t need to internally asseverate their soundbox temperature , they do n’t demand as much muscularity — which is cauterize up using oxygen — as lovesome - blooded " endotherms " do , said David Penning , an assistant prof of biology at Missouri Southern State University who was n’t involved in the Texas case .
The body of the decapitated rattlesnake
If a mammal loses its head , it will die almost now . But snakes and other poikilotherm , which do n’t need as much atomic number 8 to fuel the head , can probablylive on for bit or even hours , Penning said .
" Severing the point is n’t go to make prompt decease in the animate being , " authorship severalize Live Science . " It does n’t take that much oxygen in the first place . "
Granted , the snake might not have been ego - cognisant that it no longer had a eubstance . Rather , it likely just felt the pain from the decapitation and then tried to hold itself , Penning said .
Meanwhile , there ’s some debate about whether poisonous snakes interpose more venom into large animals than they do into pocket-size animals , and if they do , whether they consciously make that decisiveness , said Scott Boback , an associate prof of biology at Dickinson College in Pennsylvania who also was n’t involved with the Texas man ’s subject .
While thevenom questionisn’t settle down , " I would guess to guess that the reaction of a decapitated snake was just an nonvoluntary one , " and that the serpent was not verify how much venom it inject into the man , Boback secernate Live Science . This may excuse why the valet had to receive so much antivenom at the infirmary — 26 Cupid’s itch , Sutcliffe told KIII , which is far more than most affected role need .
Rattlesnake encounters
If you run into a rattler , the good option is to move away from the Snake River and go out it alone , Penning said . rattlesnake are n’t know to chase people , he noted . Instead , call your local Pisces and wildlife section , which will safely remove the Snake River . [ Shhh : A Gallery of Secretive Ground ophidian ]
If you are sting by a vicious snake , you should immediately go to the emergency elbow room , which will deal out antivenom and treat any other symptoms you have , Penning said . Pay no attention to the urban myth about sucking out the poison , and vamoose the so - shout venom - extractor kits , he tally . The body is like a sponge , and it will absorb and circulate the venom quickly , and these strategies will do more harm than in force .
Of the 10,000 mass bitten by snakes every year in the United States , between five and seven dice , Penning said . In the Texas case , the humanity was hasten to the infirmary and is now recovering .
Although demonized in popular acculturation , rattlesnakes play a vital role in their ecosystems . Because they rust so many rodents , a unmarried timber rattler ( Crotalus horridus ) can remove between 2,500 and 4,500 tick from their home base mountain chain , agree to research from the University of Maryland . ( The ticks live on the rodents . ) This , in turn , helps humans because ticks can carry Lyme disease .
