The mechanism behind this eerie behavior is a nervous system pre-programmed to make certain movements without the brain needing to send a signal.
Snakes and other cold-blooded animals such as fish and amphibians, on the other hand, don’t thermoregulate internally, instead relying on outside sources for warmth. Because their bodies aren’t generating their own heat, their energy and oxygen requirements are lower. This is how some cold-blooded, or ectothermic, animals are able to survive conditions without oxygen for periods of time.
And it’s why snakes continue to move after being bisected. As seen in the below video, the body will reflexively writhe for a time after being cut off the brain – but the head itself can remain “alive”, and likely on the defensive because of the pain of being chopped.
