Earthworms are unable to drown like a human would, and they can even survive several days fully submerged in water. Soil experts now think earthworms surface during rain storms for migration purposes.
Worms can survive underwater for several weeks as their skin can absorb oxygen from the water. However, they are unable to swim and will eventually drown if they fail to exit the water.
Oxygen diffuses about a thousand times slower through water than through air, she says. “The worms can't get enough oxygen when the soil is flooded, so they come to the surface to breathe.” Beats drowning.
Almost all worms can regrow their tails if they are amputated, and many earthworms can lose several segments from their head end and they will grow back, the Washington Post reports. For some worms, however, the more segments that are cut off, the less likely they are to be fully regenerated.
Not because they might drown. People often claim that this is the explanation, yet earthworms breathe by exchanging oxygen and carbon dioxide through their skin, which they keep wet with a slimy mucus. This means they are happiest in damp soil and most species can survive for several days under water.
Invertebrates cover a range of creatures from insects and spiders to mollusks and crustaceans. Farstad said most invertebrates, including lobsters and crabs boiled alive, do not feel pain because, unlike mammals, they do not have a big brain to read the signals.
To avoid drowning
Worms don't have lungs, but they breathe through their skin. They need moisture-enriched soil with a certain oxygen content to survive. Very wet soil won't necessarily drown a worm because they can live fully submerged for days if oxygen levels are right.
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.
Worms can live for years, usually anywhere between 4 to 8 years. It all depends on the climate and predators like birds, toads or rats. However, since the body of a worm consists of 90% water, one of the most common causes of death is when the worm's skin dries out.

Humans drown when their lungs fill with water. This is not possible for earthworms as they lack lungs. Multiple studies have also shown that most earthworm species can survive being submerged in water for two weeks or more.
Thinking and feeling: Worms have a brain that connects with nerves from their skin and muscles. Their nerves can detect light, vibrations, and even some tastes, and the muscles of their bodies make movements in response.
If there's tiny worms swimming around in your toilet, then drain fly larvae is likely breeding somewhere in your pipes. Drain flies seek out decomposing organic matter to deposit their eggs in the pipes.
85% of the weight of a worm is water and they can loose 70% of their body weight without dying. First aid for a dehydrated worms involves putting them in a glass of water for a few hours, while you rectify the wormery conditions, then put them back in the wormery.
The worms that have been reported to have been found in tap water are midge larvae, flatworms, roundworms (otherwise known as nematodes), and rotifers. The typical size of parasitic worms or helmiths, such as flukes, tapeworms, hookworms, ascris, pinworms, trichina worms, and filaria worms is 30-50 microns in diameter.
The worms survived for as long as seven hours at 122 degrees F (50 degrees C), and would spend as long as 15 minutes at 131 degrees F (55 degrees C). Water of 140 degrees F (60 degrees C) killed them.
A tiny soil worm can act like a plant seed during times of drought, going into suspended animation until a drop of rain gets it moving again. The gene that allows this survival trick is a duplicate of one already known in plants and implies a distant common ancestry.
But only the half with the saddle (which the worm needs for reproduction) survives. The other half keeps moving because the nerve endings take a while to stop firing.
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.
They burrow during the day—typically keeping close to the surface—capable of digging down as deep as 6.5 feet. The worm's first segment contains its mouth. As they burrow, they consume soil, extracting nutrients from decomposing organic matter like leaves and roots.
It takes about five months for larvae to become adult worms inside the human body. Larvae can become adults only inside the human body. The adult worms live between layers of connective tissue (e.g., ligaments, tendons) under the skin and between the thin layers of tissue that cover muscles (fascia).
About half the world's population (over 3 billion people) are in infected with at least one of the three worms forming what Columbia University parasitologist Dickson Despommier calls the "unholy trinity"—large roundworm, hookworm and whipworm.
Arguably without earthworms in our soils, life could vanish pretty quickly. We would have less food, more pollution, and more flooding. No matter how cute a panda looks, it is Darwin's “lowly” earthworms that are doing dirty, but crucial, work in the soil below.
Earthworm possess 5 pairs heart. Earthworms do not have a genuine heart because they are worms, but they do have aortic arches, which connect ventral and dorsal veins and pump blood. An earthworm is a terrestrial invertebrate, which means it doesn't have a heart and has an open circulatory system.
Earthworms, a type of annelid, have a closed circulatory system that contains five hearts. These structures are responsible for pumping blood throughout the blood vessels.
