Amazing animals that miraculously survived after their heads were severed from their necks

Flies can remove their heads. Can centipedes survive without their heads cut off? This article will amaze you with a list of animals that can survive without their heads.

You might think that losing one's head would signal the end of anyone or anything - it certainly would kill a human being.

However, some hardy animals can survive, and even perform quite impressive feats, without heads. This is largely due to some really interesting physiological differences between these animals and humans – differences in metabolism, circulation, brain size and shape, and even the ability to regenerate and regrow.

Sometimes luck plays a part, like the famous chicken on this list. What else? Read on to see what animals in the world can survive without a head! The results will surprise you and you won’t believe how resilient many species are.

Cockroach

This is the “champion” who lives the longest after being decapitated. Because cockroaches’ blood does not circulate quickly, it has very low pressure. This gives them plenty of time to “seal off” the wound, limiting the amount of blood lost.

In addition, cockroaches have a very special body structure, they have a system of nerve nodes distributed throughout the body. So if there is no brain in the head, this backup system can still allow them to function and react to external influences as usual. Cockroaches only "die" when infected and hungry.

Researchers have also proven that the head of a cockroach, after being separated from its body, can live longer if it is given nutrients and frozen.

Chicken

Surely many people have seen a chicken that has had its "throat cut" and is still able to run around the yard, but a chicken with its head cut off and still alive is truly a miracle.

It was a story that happened 70 years ago, a rooster nicknamed "Miracle Mike" in the US lived for another year and a half after being beheaded. Thanks to the owner using an eye dropper to drip milk, water, and food into his throat and using a syringe to suck out the fluid in his trachea every day, the rooster still lived resiliently.

Until one night, the chicken secreted so much fluid that the owner could not find a syringe to suck it out, so it died of suffocation.

Snake

After being severed from its neck, a snake's head can still live for about an hour.

The reason is that heat-sensing receptors located in deep grooves between the snake's eyes and nose allow it to capture heat radiation from warm-blooded prey. Thanks to the extension of nerve reflexes, these receptors remain active for a while after the head is separated from the body.

When a warm-blooded animal comes within a certain distance, these receptors activate, triggering an immediate response from the muscles in the snake's head to bite and inject venom from its fangs. The amount of venom from the severed head is still strong enough to kill the victim.

Flatworm

This animal is considered "immortal" because it is almost unaffected by losing its head.

When a flatworm's body is severed, two new worms are created. One worm grows a new head from the tail, and another grows a tail from under the body.

Praying Mantis

For male mantises, mating is a real gamble. Female mantises chew off the male’s head during mating to provide extra nutrients for their offspring. But losing their head does not affect the male mantis’ ability to fertilize females. After injecting sperm, the male mantis is trampled to the ground by the female.

Octopus

Octopuses are unique animals, with their eight tentacles not completely dependent on the central brain. Each tentacle has nerve cells, allowing the tentacles to still respond to stimuli even after being severed from the brain.

Fruit flies

Fruit flies can still fly, land, crawl and even have sex as normal when their heads are missing.

The reason is because of their special body structure, fruit flies have an “extra brain” in their chest, which replaces the main brain to help the body function normally. In addition, light-sensitive cells throughout the body of fruit flies still function when the head is lost, helping them react to light as usual.

Frog

Even if a frog's head is cut off, it can still function normally, such as jumping and swimming underwater... The reason is that the frog's nervous system does not depend entirely on the brain and the body's strong unconditional reflexes when stimulated, the electrical impulses emitted are transmitted to the muscles, requiring muscle contraction.

iguana

Aquatic salamanders are particularly famous for their regenerative abilities. They are considered immortal because they can regenerate any part of their body, from limbs, tails, to even hearts and brains.
