Contrary to popular belief, worms cut in half don't actually turn into two new worms. To a biologist, 'worm' refers to many, quite different organisms. The ability to re-grow body parts differs enormously between them, although tails are generally easier to re-grow.
For some worms, being cut between the head end and tail end will result in two fully functioning worms after the missing parts regenerate. But in some cases, the tail end of a worm will regenerate new tail segments rather than a head, the Washington Post reports.
The short answer is no. Unlike some other types of 'worm' such as flatworms and nematodes (which are very distantly related to earthworms) if you cut an earthworm in half the parts will not become two worms.
If an annelid is cut in two, they can regenerate to some degree, and in some species you can even end up with two worms. The common earthworm, however, will only regenerate from the tail end; the head end always dies.
Flatworms Are Metal. They can tear themselves in half and regrow complete bodies. They can retain memories despite decapitation. And if you chop them into little pieces, each piece will start acting like a perfectly intact worm.

Earthworms are HERMAPHRODITE, which means they are both male and female, but it still takes two worms to reproduce. In the act of mating the worms lie next to each other nose to tail almost looking like they are tied in a knot, and exchange sperm. MUCUS ring around its CLITELLUM.
The group found that earthworms produce two kinds of chemical — enkephalins and beta endorphins — which have been Identified in human brains as similar to opiates in their ability to affect sensations of pleasure and pain. The production of these substances by an animal is believed to help the animal endure pain.
Leftover soil particles and undigested organic matter pass out of the worm through the rectum and anus in the form of castings, or worm poop.
Worms don't bite. They also don't sting. 3. They are cold-blooded animals, which means they don't maintain their own body heat but instead assume the temperature of their surroundings.
The breeding cycle is approximately 27 days from mating to laying eggs. Worms can double in population every 60 days.
No, both worms cannot get pregnant as only one worm carries and incubates the fertilized eggs or offspring at a time. However, some species of worms, such as composting worms, are hermaphrodites, meaning they can exchange sperm with another worm to fertilize their own eggs.
Baby worms develop in cocoons. They are babies for 60 to 90 days and it takes them about a year to become an adult. Worms can live for up to 10 years. Worms don't have a stomach.
Don't be fooled though, they make up for it with the interesting aspects they do have. Like five hearts that squeeze two blood vessels to push blood throughout their little bodies. Earthworms have mucus and little hairs covering their skin that allows them to move through different types of soil.
Worms don't sleep on a day/night schedule like mammals. Instead, their sleep-like behavior occurs at specific stages during development; the worms enter this state each time they transition from one larval stage to another.
Many scientists agree that worms tend to use soaked soil days as migration days. They can't travel as fast while burrowing tunnels under the ground, and it's too dry above ground on rain-free days for them to survive. So, a soaking rain allows them to slither to the surface and move gracefully on the wet ground.
When worms die in the bin, their bodies decompose and are recycled by other worms, along with the food scraps. Worm castings are toxic to live worms. After all the food scraps in a bin are recycled, the worms will eat their own castings which will poison them.
Worms hate: meat or fish, cheese, butter, greasy food, animal waste, spicy and salty foods, citrus.” The food-to-worm ratio is not precise, nor is the amount of castings they will produce. The rule of thumb is that a pound of worms will eat one to two pounds of food in a week.
You'll likely need to give your doctor a stool sample for a few months to make sure all the worms are gone.
Earthworm's nervous system explained
If we observe an earthworm's behaviour, we can see that they react strongly if something occurs that may cause them pain. For example, if an earthworm gets salt on its skin, or if it is cut in half, it will wriggle fiercely, as if trying to escape.
Norway might have considered banning the use of live worms as fish bait if the study had found they felt pain, but Farstad said "It seems to be only reflex curling when put on the hook ... They might sense something, but it is not painful and does not compromise their well-being."
Yes, it is now accepted that worms feel pain – and that includes when they are cut in half. They do not anticipate pain or feel pain as an emotional response, however. They simply move in response to pain as a reflex response. They may curl up or move away, for example, from painful or negative stimuli.
Earthworms only communicate with each other by touch and taste, but they can feel vibrations, and often avoid predators by sensing their footsteps.
But it wasn't until researchers brought them to the lab that they noticed how noisy they were. When the creatures fight, they wriggle toward each other, contract their bodies, and launch themselves headfirst at their opponent, the team found.
