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.
Can worms drown? 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.
They might sense something, but it is not painful and does not compromise their well-being."
Water makes up more than 75% of the earthworm's body weight, so moist soils are preferred to prevent dehydration. Earthworms acclimate quickly by moving to humid sites or by entering a resting state.
It should have the consistency of a wrung out sponge. If water leaks out between your fingers – then it's too wet. (If it's dry and crumbly… it's too dry.) If your worm bin is outside rain can get in through the loose fitting lid or through the air holes.
Worms like red wigglers need a damp, but not wet, environment to thrive. The ideal amount of water in a worm bin is just enough to produce 1-2 drops of water when you squeeze a handful of bedding. Think about your yard or a local park, if you dig down a few inches the ground is usually moist but not dripping wet.
However, earthworms can survive if their tail end is cut off, and can regrow their segments but earthworms generally cannot survive if the front part of their body between the head and the saddle is cut as this is where their major organs are.
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.
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.
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.
Anytime you handle a worm there are a few simple rules to follow: Keep the worms skin damp. You can accomplish this by spraying water on a plate to let it move around on, or use a damp paper towel. Make sure to keep you hands damp if you hold a worm.

Earthworms are hermaphrodites, meaning an individual worm has both male and female reproductive organs. Earthworm mating typically occurs after it has rained and the ground is wet. They emerge from the soil and jut out their anterior end.
Elephants, cats, flies, and even worms sleep. It is a natural part of many animals' lives. New research from Caltech takes a deeper look at sleep in the tiny roundworm Caenorhabditis elegans, or C. elegans, finding three chemicals that collectively work together to induce sleep.
Blood is carried to the front of the earthworm's body by dorsal blood vessels, while blood is carried to the back of the earthworm's body by ventral blood vessels. The earthworm has 10 aortic arches, or 5 pairs.
That's right, four out of every five animals on earth are nematode worms. Microscopic soil nematodes in action. Microscopic soil nematodes in action. A new study of soil nematodes co-authored by Adams reveals that there are 57 billion of them for every single living human being — much greater than previously estimated.
These 10 individual “hearts” or aortic arches line the central body cavity and their mechanical pumping action facilitates the circulation of the earthworm, much like a human heart does.
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.
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.

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 are ready to breed once they mature from 50 to 90 days. Earthworms are hermaphrodites; they can be male or female (a great advantage!). They can perform both male and female functions and mate every 7 to 10 days. The mating process takes around 24 hours.
A worm's skin is photosensitive and therefore they need a dark environment. Because worms have no teeth, they need some type of grit in their bedding that they can swallow and use in their gizzard to grind food, much like birds do with small stones.
