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.
7. Worms can live as long as four years. 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.
By their activity in the soil, earthworms offer many benefits: increased nutrient availability, better drainage, and a more stable soil structure, all of which help improve farm productivity. Worms feed on plant debris (dead roots, leaves, grasses, manure) and soil.
Worms help to create good soil structure
Earthworms burrow into soil, which creates air pockets. These tunnels aerate the soil, allow water to drain and decrease the rate of erosion by up to 50 percent, which reduces runoff and prevents drought, flooding and other harmful effects of climate change.
Worms help to increase the amount of air and water that gets into the soil. They break down organic matter, like leaves and grass into things that plants can use. When they eat, they leave behind castings that are a very valuable type of fertilizer. Earthworms are like free farm help.
Heartbeats: Worms don't have just one heart. They have FIVE! But their hearts and circulatory system aren't as complicated as ours -- maybe because their blood doesn't have to go to so many body parts. Moving around: Worms have two kinds of muscles beneath their skin.
There are about one million species of worm, living in a wide range of habitats.

OSLO (Reuters) - Worms squirming on a fishhook feel no pain -- nor do lobsters and crabs cooked in boiling water, a scientific study funded by the Norwegian government has found.
But animals with simple nervous systems, like lobsters, snails and worms, do not have the ability to process emotional information and therefore do not experience suffering, say most researchers. "There are two types of animals, invertebrates and vertebrates," said Craig W.
(Learn more about creating a worm composting bin.) 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.
If the anterior part of the earthworm, which includes the brain, is amputated, the worm would essentially survive even in the absence of the brain. In these brain amputee-derived worms, the nerve cord serves as the primary control center for neurological function.
You can credit your existence to tiny wormlike creatures that lived 500 million years ago, a new study suggests. By tunneling through the sea floor, scientists say, these creatures kept oxygen concentrations at just the right level to allow animals and other complex life to evolve.
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.
If an earthworm is split in two, it will not become two new worms. The head of the worm may survive and regenerate its tail if the animal is cut behind the clitellum, according to The Washington Post.
No, not really. Instead, they have cells called receptors that can sense whether it's light or dark. This allows worms to tell if they're underground or above ground.
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 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.
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).
Although composting with worms - or vermicomposting - is generally seen as the more efficient method, it is absolutely possible to compost indoors without worms! Another method of composting is aerobic composting, which you can easily accomplish indoors, even if you currently live in an apartment.
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.
The consensus among researchers such as Shuker and author Richard Freeman is that the Mongolian Death Worm likely does not exist, and the belief is instead based upon sightings of either a type of limbless reptile known as worm lizard (which resembles a large worm, burrows underground and can reach several feet in ...
Octopuses or octopi (both are technically correct) are one of the most well-known animals with multiple hearts.
Worms are also unusual, with five structures called aortic arches acting as basic hearts. The hagfish, sometimes called the slime eel, has one true heart plus three accessory pumps helping the blood to move. Just when you thought you had heard it all, some animals are heartless.
