In fact, these friendly fish are a favorite among scuba divers. The wolf eel may be scary looking and may have a powerful bite, but these fish aren’t aggressive. It will attempt to bite whatever it can – even its own wriggling body. 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. This is how some cold-blooded, or ectothermic, animals are able to survive conditions without oxygen for periods of time.Īnd it’s why snakes (and other reptiles) continue to move after being bisected. Because their bodies aren’t generating their own heat, their energy and oxygen requirements are lower. 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. And a decapitated venomous snake head is evidently pre-programmed to bite in response to a stimulus-such as a someone trying to pick it up, he said. The mechanism behind this eerie behavior is a nervous system pre-programmed to make certain movements without the brain needing to send a signal. It’s a similar reflex to that of a headless chicken being able to run around for a short time, Jayne says.

The bodies of snakes often writhe around for some time after they are dead, says Bruce Jayne, a biology professor at the University of Cincinnati. In June 2018, after a man in Texas was bitten by a decapitated rattlesnake head, National Geographic and Science Alert penned articles explaining the phenomena: It’s likely that the fish’s nerve endings were still functioning, and that pressure near its jaw triggered a muscle spasm. The original video shows that this fish was decapitated just before a Coke can was pushed into its jaws. While some viewers hypothesized that this fish head was still alive when this video was filmed, it’s likely that the footage shows an involuntary muscle reflex. The original video also provides some insight into how and why this decapitated fish head bit down on a can of Coca-Cola.
