An earthworm has a streamlined body with no antennae or fins or arms or legs! This streamlined shape is an adaptation to living in narrow burrows underground and the need to move easily through the soil. An earthworm has circular muscles that surround each body segment.

1: it has slimmy skin which helps it to move in the soil. 2: it has pores on skin through which it can breathe even inside the soil.

Earthworms and their relatives live anywhere there is moist soil and dead plant material. All earthworm species need moist soil conditions to survive. Most earthworms species live in the top meter or so of soil, and spend much of their time just below the surface where there is plenty of decomposing plant material.

A mixture of soil and organic matter within an earthworm burrow. Earthworms incorporate large amounts of organic matter into the soil. Some worms live in permanent vertical burrows such as these. Others move horizontally near the surface, filling their burrow with casts as they move.

They improve soil structure, water movement, nutrient cycling and plant growth. They are not the only indicators of healthy soil systems, but their presence is usually an indicator of a healthy system.

Some earthworm gut-associated microbes, such as Streptomyces, are known to produce cellulases, which would help the earthworm host to degrade plant residues, while other gut microbes, like Mycobacterium utilize common soil components, such as humic acids (see [11] for further discussion on the ecological roles of …

In the intestine, food is broken down into usable chemicals which are absorbed into the bloodstream. 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. Worm poop is dark, moist, soil-colored, and very rich in nutrients.

“We already know that worms do harbour bacteria that cause human disease (pathogens). “Pathogens that we already know can be carried by worms include E. coli O157 and salmonella. These bacteria can cause severe gastrointestinal infections in humans and are commonly found in soil.

As a company that specializes in vermiculture, we often get asked, “Can you eat worms”? The short answer is yes. These squiggly creatures can be eaten raw or cooked, especially for small children who are invariably drawn to earthworms. Wild worms can carry parasites and germs that can be harmful.

When the rain hits the ground it creates vibrations on the soil surface. This causes earthworms to come out of their burrows to the surface. Earthworms find it easier to travel across the surface of the soil when it is wet, as they need a moist environment to survive.

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.

It’s true! Of those thousands of types of worms, over 2,700 of them are species of earthworms. These earthworms never burrow deep into the soil, so cold winter temperatures kill them. To keep their species alive, however, they lay eggs in tiny sacks that protect the eggs from freezing or drying out during the winter.

Redworms should be protected from freezing temperatures. Temperatures below 50 degrees F. slow down worm activity.

No worms at all? It means that the conditions must be poor – no moisture, toxic substances, sandy soil, or no organic matter for them to eat will all prevent them from setting up shop in your yard.

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.

Since man began making tools, he has been baiting fishhooks with worms, generally assuming that a worm impaled by a hook feels no pain.

Earthworms use water for many things — for respiration, to keep their bodies from drying out, and to make the mucus that helps them slide through the soil. When soils get dry, earthworms go into estivation. The ability of earthworms to go into estivation suggests they can survive dry periods in the soil.

When soils get dry, earthworms go into estivation. Inside that chamber, the humidity is higher so they don’t dry out as the soil dries.” The ability of earthworms to go into estivation suggests they can survive dry periods in the soil.

If a worm’s skin dries out, it will die. This happens because the worms’ homes in the soil got flooded, and the worms came to the surface in search of less soggy conditions. Once on the pavement, worms often get disoriented and cannot find their way back to the soil. They then dry up and die when the sun comes out.

Worms are incredible earth movers. The organic matter they deposit within their tunnels helps to break down rocks and minerals from deep in the subsoils and bring them to the surface as living soil.
